ABSTRACT: Two modets of a high-pressure (up to 18 kbar) chamber used for studying
single ciYetals of metals and semiconductors in a magnetic field at liquid
helium t mperatures are described. The chambers (6.5 mm inside diameter)
are madeiof heat-treated beryllium-bronze and the pistons are made of
TSM-322 corundum-microlite heat treated to a haviness of 75-78Rc. The
required pressure is created in the chamber at mm temperature by a
hydraulij press. The chamber is then sealed mechanically and placed in a
Dewar vessel containing liquid helium. Pressure in measured by mans of
maaWin and superconducting pressure gages. The magnitudes of anisotropy

of uwignitip resistance and of quantum oscillations of electric resistance
of zinc, mpasured in the chamber, showed that the compression was close to
hydrostatiii. The heat expansion of the materials used for chamber con-
struction Vere tested at temperatures from 77K to 20C. It was found that
the heat expansion coefficient of corundum-microlite is significantly
smaller than that of beryllium-bronze. Thus, using a second material in
the chamber should not lead to pressure ]Losses when the temperature drops.

Gaydukov, ZhETF v. 45, 71, 1963), was studied further with the aid of a new bomb,
capable of producinp pressures up to 18,000 kg/cm2 at h,~lium temneratures. The
new bomb is illustrated In Fig. 1 of the Enclosure. Tta main advantages are that
its container is self-sealing and that its moving parts are made of solid non-
magnetic materials. Measurements were made without pre3sure and at 11,100 and
15,900 kg/cm2 in fields ranging from 2000 to 11,000 oe. The results show conclu-

sively that the oncillations of the electric resistance of zinc decrease abruptly
with increasing pressure, and are in good agreement with theoretical calculations
based on the model of W. A. Harrison (Phys. Rev. v. 118, 1190, 1960). The results
also confirm the existence of a needle-like electronic psrt of the FernA surface
of cadmium, which should become obi3ervable at the higher pressures attained in the

ABSTRACT: Data are given/from an experimental study of t direct effect which hy-
0 g/cm2 has on the e
drostatic pressure of up ~o 800 k ffectiv4mass of electrons. The
experimental method was based on tfie new Gurevich-FEr-5011 magnetophonon resonance
phenomenon. The specimen studied was a single cry3tal of n-type InSb with dimen-
sions of 2 x 2,5 x 16 mm, a concentration of 8-10-13 cm-3 and a mcbility of 7-105
CM2/v-sec at 770K. The relative reduction in the linear dimensions of the crystal
was no greater than 0.6% at maximum pressure. Curves am given chowing the trans-

verse magnetoresistance as a function of magnetic field strength at various pres-
sures. Formulas are given for determining the effective mass of electrons from the
period of the oscillations and from the position of the individuil maxima on these
curves. Calculations show a change in effective mass frcm 0.016 to 0.025 when the
pressure is changed from 1 kg/cm2 Uo 8000 kg/cm2. Since the width of the forbidden
zone in this pressure interval increases by a factor of 1.5, the experimental data
confirms the theoretical conclusion of direct proportionality between the effective
mass of electrons and the width of the forbidden zone for an InSb crystal in this
pressure interval. Orig. art. has: 3 figures, 3 tables.

fault localization in wave-wound or lap-wound armatures without equalizers,
consists of a pulse generator and an oscilloscope. The pulse-generator

The author demonstrates theoretically the possibilities of lo-
cating defective Insulators by the wave method. He also presents
the results of checking the proposed testing methods under actual
operating conditions. There are 5 Soviet references.
