The technique for deter- mining measured values,requires no observation of special conditions in setting up the tests ' except the maintenance of uniformly symmetrical heating (and cooling) of samples in an environment of constant temperature. Cylinders of magnesite, fire clay, and foamy fireclay were used in the.experinnnts, and measurements were made by reeans of Chromel-Alumel thermocouples with thermoelectrodes 0.2 mm in diameter, connen.ted to an EPP-09 electronic potenticAneter. Errors in measured temperatures did not exceed 2%. The method is simple and needs no special heating device. It can be used in any plant laboratory and permits determination of tbnrmal properties Card 1/2 - , I . lWF 7~~7i~f -F kAt BRATCHIKOV, S.G.; BAZILEVIGH, S.V.; YAROSHENKO, Yu.G.; MAYZELI, G.M.

However, such data are not available on cold rolled sheet. This paper contAins some data on the variation of these properties in cold rolled 0.35 mill thick and 0.50 mm thick transformer sheeis. The data were obtaLned by means of Epstein apparatus. For detailed study of the nonuniformity of the induction of cold rolled transformer steel, sheets 1500 x 240 x Oo35 mm were investigated by means of simple apparatus, the basic circuit of which is shown in Fig.l. It consists of plywood frames:- placed on top of each other, 1400 mm long with windows of 20 x. 260 mm. A metering coil of 600 turns is mounted on the central part (3/5ths of the length) of each frame. The magnetiza- tion winding surrounds both frames and has 522 turns, which are Card 1/7 S/520/59/000/022/019/021 E073/E535 on the Sheet by Sheet Nonuniformity of the Magnetic Properties of Cold Rolled Electrical steel distributed longitudinally as followS3 Number of 89 44 4-5 41 42 42 41 45 44 89 Total turns 522 Length of 14 14 14 14 14 14 14 14 14 14 Total the sectian 140 (cm) The resulting longitudinal distribution of the induction in a pair of equal sheets placed into the solenoid is plotted in Fig.2. The indicating instrument is a magnetoelectric one, which is series connected with a half-wave controlled bridge rectifier made up of equal cuprous-oxide elements. The instrument is shunted with a smoothing condenser and with a resistance for the purpose of adjusting the sensitivity. The indicator coils are connected in a differential circuits The control voltage is obtained from a supplementary win ding with 80 turns, which are wound on a central Card 2/7 S/520/59/000/022/019/021 E073/E535 I.On the Sheet by Sheet Nonuniformity of the Magnetic Properties of Cold Rolled Electri*cal Steel ipart.of the solenoid; the control voltage is several times the value of the e.m.f. difference in the metering windings, as a result of which the rectifier circuit is piactically blocked for a half-cycle of the control voltage, whilst during the other half- cycle it shows only a low resistance to the current flow in the :metering coils, regardless of the direction of the current (this lis necessary for ensuring an unequivocal relation between the -;readings of the measuring instrument and the difference in the amplitudes of the induction in the "standard" and the tested sheet 'The instrument Is fed from'a.c. mains via an autotransformer.

By means of this instrument two batches of cold rolled-steel were sorted out Card 3/7 S/520/59/000/022/019/021 E073/E535 :On the Sheet by Sheet Nonuniformity of the Magnetic Properties of Rolled Electrical Steel ;which, as regards induction, were.rejects from ordinary tests. ~The results obtained by the Epstein method for 0-35 mm sheet before after sorting on the basis of induction values were*as follows: Table 4.

A real increase in the testing accuracy can be achieved only by increasing Card 5/7 S/520/59/000/022/019/021 E073/E535 On the Sheet by Sheet Nonuniformity of tile Magnetic Properties of Cold Rolled Electx*.cal Steel .very considerably the number of sheets tested within each batch. It is recommended that this can be done by means of the instrument described in this paper-, using as a criterion the induction Blpy or B2~ since the quantity of sheets scrapped due to unsatisfhcto lo s values is only a fraction of that scrapped due to unsatisfactory induction. It would be advisable to combine the system of preliminary sorting of sheets on the basis of induction with subsequent more accurate evaluation of each batch by means of apparatus which permits obtaining absolute values.

TITLEt Relation Between the Magnetic Induction of Cold-Rolled Transformer Steel and the Conditions of Final Annealing ~6 PERIODICAL: Stall, 19609 No. 8, PP- 750-752 _a~ali~n'of cold-rolled transformer TEXT: The effect of final anne i steel in vacuum on magnetic induction in weak and medium fields is not sufficiently clear. Many steels with high induction capacity in strong fields display relatively low induction in weak and medium fields. In order to investigate this problem, tests were carried out with three kinds of steelsz 6260 (SiO-16%), 6247 (Si:3.23%) and 6230 (SiO-10%)- Until a 0-35 mm thickness of the sheet was obtained the technological process took place according to the conventional methods. Final anneal- ing was carried out in vacuum electric furnaces up oto 1,1500C for 30 hours. The.metal was cooled by the furnace to 600 C, after removing the hood cooling was continued to 2500C under a muffle in a protecting gas medium. Test specimens (0.35 x 30 x 250 mm; 1 kg) were made of all three types of steel, the magnetic properties were determined by the Card 1/3 S/133/60/000/008/011/013 Relation Between the Magnetic Induction of Cold-Rolled Transformer Steel and the Conditions of Final Annealing Epshteyn ballistic method before and after the additional annealing which was the main feature of the new process. Type 6260 was cooled by the furnace between 6000C and 4500C to.various degrees and the types 6247 and 6230 were tested in 6 charges, three of which were cooled by the furnace to 6000C and three to 4500C- The results obtained with the 6260 type specimens showed that in proportion to the decrease of the temperature, at which the hood is removed, the magnetic properties in weak and medium fields improve; magnetic induction B 0 M increases from 1.25 to 1.62 gauss, B0.008 from 10.11 to 25.10 gau;s Fig. 1A) and B Ifrom 12,680 to 14,650 gauss; the coercive force H increases from 0.18 to 0.13 oersted, maximum magnetic permeability/.z., from 18,280 to 36,380 gs/oersted max Fig. 2),q the plasticity of the metal increases from 2.7 to 18 bendings. This change in the magnetic and plastic properties can be explained by a more thorough distribution of the internal stresses upon the removal of the hood at a lower temperature with a corresponding re-distribution of the admixtiires (Ref. ~). With additional annealing of the specimens at 7500C, in order to eliminate work hardening due to cutting, the Card 2/3 S/133/60/000/008/011/013 Relation Between the Magnetic Induction of Cold-Rolled Transformer Steel and the Conditions of Final.Annealing improvement of magnetic properties can be maintained. The results obtained with specimens of 6247 and 6230 type steels agree with the results of the 6260 type specimens. Generally, it was found that after the additional annealing of specimens to eliminate the work hardening due to cutting, the yield of products complying with F'OCT (GOST) 802-58 increased from 40% (in the conventional cooling by furnace to 6000C) to 80%, when cooling with the furnace to 4500C.

It was also apparent that tests by the Epstein square give only very approximate indications of the properties of the batch.

However, it in sufficient to limit a test to measuring a .single quantity, for instance B25 The following conclusions area arrived at: 1) Individual 'sheets of cold-rolled electrical steel differ considerably in their magnetic properties. no 2) The induction B25 is one of 'the most reliable guides of the quality of cold-rolled electrical steel.

The Problem of theThgoing Cross Section of Holes in Germahium by Defects Formed by Gamma Irradiation Ig Fizika tverdogo tela, 19609 Vol. 2, No- 4, PP. 566-56a TEXT: The trapping cross section of holes by defects formed by neutron bombardment vas found to be - lo-15 cm2 (Refs. 1-3). The trapping cross section for gamma irradi&tion was 4 .10-16om2. The present paper shows that this difference is due to a false assumption: A defect formed by gamma irradiation has not two but four acceptor levels in the forbidden band. The dependence of the lifetime on the irradiation with gamma quanta was determined on 11 specimens, wherefrom the trapping cross section of the holes was calculated (Table). A Cobo preparation with an activity of 400 gram-equivalent Ra was used as gamma source. The authors used the photomagnetic method, the method of photodiffusion, and the examination of the relaxation curves of photoconductivity to measure the lifetime. The mean value of the trapping cross section was found to be 3.8-10- 15cm 2. This is close to the value obtained for the neutron Card 1/2 819W4 The Problem of the Trapping Cross Section 5/181J60/002/04/02/034 of Holes in Germanium by Defects Formed B002/Bo63 by Gamma Irradiation bombardment (3-10-15cm2 in Ref. 1).

TITLE: The Influence of Adhesion Levels on the Relaxation of Non- equilibrium Conductivity in Germanium Irradiated With Gamma Rays 7\ PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 8, pp. 1966 - 1977 TEXTt In order to stixdy the mechanism of recombination processes of defects, the authors made a number of experiments which are described here and whose results are discussed in detail. The main purpose of the experiments was to determine the effect of 7-induced defects on the ,temperature dependence of the relaxation time of the conductivity of n-type germanium. First, the method and the experimental arrangement are 3 discussed.-n-type Ge single crystals of 5 - 5 - 15 mm , etched with CF-4 (SR'4) to reduce the rate of surface recombination, served as ,samples. They were exposed to ?,-rays of 120 r/sec (Co 6o ) at 200C. The concentration of the resulting structural defects was determined from Card 1/4 --- - ------- 1 83022 The Influence of Adhesion Levels on the S/181/60/002/008/041/045 Relaxation of Non-equilibrium Conductivity in B006/BO63 Germanium Irradiated With Gamma Rays formula Nt M '6N.J, where 0 ist the V-f lux per am2of the sample surface, NGe the concentration of the germanium atoms, and a the cross section of defect formation which was assumed to be 6 - 4-3-10-27cm2 according to Ref. 6. The experimental arrangement is schematically shown in Fig. 1. The sample is placed in a cryostat between the poles of an electromagnet which can generate a field of up to 4,000 oersteds. This cryostat permits a change in temperature from room temperature to that of liquid nitrogen. Fig. 2 shows the temperature dependence of the relaxation time, T', of non-equilibrium conductivity as the function Inil - f(I/T). The six 13 -3 curves refer to six Jifferent Nt-values between zero and 1.0-10 am With inoroaning Irradiation, a dropping slope of the curves having a minimum could be obt,erved. After passing through this minimum, they steeply rose again. Thus, the relaxation time first decreased with dropping temperature and again increased with further dropping tempera- ture.

The values found for the second sample deviate but little from those of the first sample; the second sample had a somewhat lower resistivity. The numerical values are compiled in a table (P- 1976).

TITLE: Investigation of the kinetics of impurity photoconductivity for the purpose of determining the parameters of local levels PERIODICAL: Fizika tverdogo tela, V. 3, no. 1, 1961, 252-266 TEXT: An investigation of impurity photoconductivity is not only of interest in principle, but is also of practical importance for studying the local electron states in the forbidden band and especially of its interaction with exciting radiation. Apart from an earlier paper by the authorst relaxation processes of impurity photoconductivity have hithert not been investigated in detail; this was, however, the aim of the present voluminous paper. The authors set themselves the task of investigating theoretically the most important cases of photocurrent relaxation during excitation in the impurity region. The rules governing the kinetics of impurity photoconductivity have certain peculiar features as is shown Card 1/6 IS11811611003100110361042 Investigation of the kinetics of.*. B102[B204 here, due to which impurity photoconductivity relaxation differs essentially from that of intrinsic photoconductivity. An exact analysis of these rules shows that an experimental investigation of the kinetics of impurity photoconductivity may serve the purpose of determining various parameters of impurity centers as, e.g., the photon capture cross section, the trapping cross section for free carriers, as well as the energy position of the impurity level in the forbidden band, the concentration of centers and the degree of their completion. In part 1 of this paper, the most important rules of the kinetics of impurity photoconductivity in the excitation of carriers for one type of local centers are dealt with. This is done on the basis of an example of a semiconductor, in whose forbidden band there is a sort of local level with concentration M; these levels are assumed to be in the upper half of the band, so that they are in heat exchange with the conduction band. This semiconductor is irradiated with monochromatic light of such a wavelength that only electrons pass from the local levels onto the conduction band, and that monopolar impurity photoconductivity occurs.

Low-temperature breakdown in germanium in connection with TITLEt radiative defects PERIODICAL: Fizika tverdogo tela, v. 3, no. 4, 1961, 1298-1300 TEM In germanium doped with elements of the third or fifth group, the current may suddenly rise at helium temperatures when the field applied exceeds a certain critical value. This effect is known as low-temperature breakdown. The following is the mechanism of this effect; At these tempera- turesp the majority of carriers causing impurity conduction is localized at impurity centers, and resistivity is high. When a field is appliedf the free carriers are accelerated and, at a certain field strength, their energy is high enough to cause impact ionization of the filled impurity centers, The low-temperature breakdown in Ge or Si due to donor or acceptor impurities has been investigated repeatedly. The present paper is a report on studies of this effect which is caused by radiative defects; such defects have been ,---Card 1/4 22064 S/18 61/003/004/030/030 A. B102 209 Low-veinporature ... YB produced by irradiating the semiconductor with gamma quanta or fast neutrons. First, the energy levels of the radiative defects are discussed; Fig. 1 shows the level scheme for gamma-irradiated (a) and faat-neatron irradDateft (b) germanium. The two shallow levels of the radiative defects axe only 0.02 and 0.01 ev, respectively, off the valency bandl at helium temporatur,r"', they are occupied by electrons only partly or not at all. In neutron-iv- radiated Go specimens, the 0.01-ev level was found to be free from clectrcais at helium temperatures. In chemically impure specimens, the presence of donor centers offered a certain compensation, and the level wa8 partly oc- oupied by electrons. Volt-ampere characteristics of such specimens were taken by means of a "characteriograph.11 They were analogous to those ob- tained by B. Vul, E. Zavaritskayal and V. Chuyenkov for the low-temperature breakdown due to impurity centers. Altogether; three specimens were examin- ed; gamma-irradiated 1-,r had a concentration of shallow radiation levels of Na - 7-jol3cm-3 and a hole concentration on them of p a = i.iol3cm-3; 1-n and 2-n were n-type specimens having a resistivity of 2 ohm-cm; after neutron irradiation they were p-type. n-type and p-type specimens having a resistiv- itY Of 3 and 12 ohm-cm, respectively, were measured for comparison.

TITLEs Impurity photoconductivity with gamma-irradiated germanium PERIODICILi Fizika tverdogo tela, V. 3, no. 10, 1961, 3211 - 3219 TEXTs gamma irradiation of n-type germanium gives rise to an appreciable impurity photoconductivity which exceeds that in nonirradiated germanium by some orders of magnitude. 'It was examined in n-type germanium specimens (Q - 20 - 30 ohm-cm irradiated with Co 80 quanta. Since irradiation took place at .INC, the radiation defel were stable at room temperature. The experimental setup is shown in Fig. 1. The specimen was placed in a cryostat with Or- indow. All measurements wero made at N1000K. Parasitic light was eliminated by a set of filters. The gamma-induced defects in n-type Ge form four levels in the forbidden band which are 0.02, 0.11 and 0.*26-ev above the edge of the valence band and 0.2 ey below the bottom of the conduction band. The Fermi level was con- siderably above the level at 0.2 ev throughout the temperature range in- volved. The typical dependence of this photoconductivity on the energy Card I 29qO2 5/181/61/003/010/032/036 Impurity photoconductivity... B125/B102 of incident quanta is presented in Fig. 3. The relaxation of unipolar impurity photoconductivity was also examined. In these experiments, the light frequency was chosen such that electron transitions occurred only from the 0.2-ey level. Growth and decay curves of photoconductivity, when, respectively, switching the light on and off, are "asymmetric" and do not obey the exponential law. The experimental results may be explained by calculations of S. M. Ryvkin et al. (FTT9 III, no. 1, 1961). quenching was obseryed in all n-type specimens when irradiating simultaneously by light corresponding to the self-absorption band and the impurity band. Fig. 5 presents typical curves of quenching spectra. The complicated characterl the great variety of relaxation curves, and of spectral proper- ties of querohing are due to the superposition of two concurring processes, namely, of quenching and of the impurity photoelectric effect. The shape of the spectral distribution curve, while depending on the ratio between the two light intensities depends on the experimental conditions and is not characteristic of the examined material. Conclusionst The radiation defeats forming as a result of gamma irradiation of germanium gives rise to an impurity photoconductivity reaching as far as 6 microns.

To explain the damage mechanism and kinetics, the effects of pulse energy, focus position, temperature, and the focal length on the nature and extent of the damaged region were investigated. The experimental dataindicate a strong dependence of 'the nature' and extent of damage on the test material and the operating (peak or total energy) eonditions. The damage in each spot occurred independently and was caused by beams of a small critical density. Die most probable damage mechanism. is thought to be the coherent hypersonic phonons generated as the result of Brillouin scattering. The.thermal explosion accompanying damage due to hypersonicphmorij in the 'case of strong optical dbsorption is suggestea as a secondary mechanism. The experiments showed that the thermal explosion occurred I basically near therfocus and that its role varied with materials and energy density.

The character of the breakdown was examined under a microscope and its size measured with a horizontal comparator.

Estimates of stresses caused by the hypersonic wave due to the laner,beam in- dicate that local effects play a substantial role in the breakdown process. In the case of an ordinary laser pulse, the breakdown mechanism is governed by the peak power, whereas in the case of a giant pulse the decisive factor is the total energy. The cause of the breakdown is shown to be connected with the action of coherent acoustic pbonons generated in the course of a stimulated Brillouin scattering, thermal effects being secondary. Study of the breakdown makes possible compari. son of volume and surface strengths of the material and can be used to evaluate the time of phonon coherence loss, which Is found to be of the order of 6 Rsec for poly- methyl methacrylate.

In view of some unusual.-featurea of the ob- served paramagnetic centers (absence of macroradicals and absence of hy-perfine struc- ture), it is difficult to draw definite conclusions concerning their nature, but it is suggested that they may be the results of the decomposition of the polymers under the influence of the laser beam. The differences between the centers-of PMMA and PS may be caused either by differences in the centers themselves, or by differences in their local concentration. Orig. art. has: .3 figures.

The present article deals with the effect of the ener- gy contained in the laser pulse on the general evolution of damage to aingle-crystai LiF and describes the dislocation structure in the cleavage surfaces. The experi- mental procedure is similar to that described In the earlier paper. A pulsed neoOymium glass laser was used, with the light beam directed always along the (001) crystal axis. Dal3age occurred at pulsed energy density exceeding 100 J/cp2. corresponding to 1-, 0.2 x 100 Wcm2. At this threshold value, damage usually started Card 1/2 L 45783-66 ACC NRs AP603o966 with a single crack e (001) plane, perpendicular to the beam direction.

Tibe ex- perimental procedure was the same as in the earlier investigation. 71he radiation source was a neodymium laser operating in the ordinary-pulse mode. The tests con- sisted.of determining the influence of energy on the number of irradiations necessary! for the first visible crack in the material to appear, or the change in the dimensioW of the damaged region with changing number of pulses. Comparison of the results of the two tests has shown that the true threshold of optical strength is approximately one-third as high as expected from an analysis of results of damage produced by single irradiation. An investigation was made of the nature of the irreversible changes due to the fatigue occurring at pulse energies lower than critical (necess ary.

It is thus concluded that fatigue effects must be taken into account in stu- dies of damage to transparent materials by laser beams. The authors thank I. A.- Kodaneva for help withthe experiments.
