resulting product was cr (SG)~ Silica gel. Type crti(SGM) was obtained by
treating SO, with liquid trimethyl chloro silane. The analysis of SGII for
C content showed that 100 A of.the SGM surface contained 1.22~- C' i.e.,
on an average, 2-7 trimethyl.chlo ro silyl groups. This corresponds to a
coating by organosilicon film of an:almost maximum density. Prior to the
adsorption experiments, the samples were heated for a fairly long time
in vacuum adsorbers in small suspended quartz crucibles at 1500C and a
pressure of 1-io-5 mm-Hg. In the range of pressure ratios of p/p. from 0
to 1, isothermal lines were.obtained for the adsorption and the
desorption of benzene'vapor. In the.case of SG the isothermal line
deviates sharply toward the:.lower.right side. With the beginning of the
capillary condensation the hysteresis curve shifts from p/ps - 0.2 for SI
to P/ps - 0 75 for SG. At p/ps = 0 1 1 the benzene adsorption a on SI and
SG equals 2;mole/m2, whereas a. O.;Amole/m2 for SGM. In other words, the
benzene adsorption drops-to the 20th part with the chemical modification

TEXT: The surface of aerosil-was modified with ethylene Mlycol to reduce
the adsorption energy and pres'erve the hydrophilic character and aelective-
action of functional groups. Etherification of silanolgroups with ethylene
'glycol -Si-OH + H0C2R4 OR _Si_O_C 244 OR + U20 causes coating of the
aerosil surface with.ethylene glycoxy groups, one hydroxyl group of which.is,

groups located on the surface of hydrated silica were substituted. The
adsorption isotherms of substituted aerosils showed that the adsorption
of nitrogen, n-hexane) and argon vapors was riot affected but that of
benzene and methanol vapors rapidly reduced. This reduction is due to
chemical changes of the surface and their effect on adsorption since the
sDecific surface o-r ~,erosil is hardly changed by etherification. In a dense
monolayer, the area per molecule is '06 811 /aM11, where aM is the capacity
2
of the monolayer, a N is the specific surface. Substitution of ethomy for

silanol groups causes decrease in a for methanol and benzene. With nitro-
m
gen andmethanol the equilibrium. constant decreases with increasing substitu-
tion degree. Grafting may be;applied to diol substitution: (1) to one or
two OH groups; (2) to -Si-O-Si- bridges, and (3) to bridges and OR groups.

for its purpose to Install huge accelerators whose construction requires large
resources outlaid and long time. For work on colliding electron-electron, Iposi-
tron-olectron, and proton-proton beams, throe In3tallations are being built, which
are In various stages of readiness. Work on colliding electron beams was con-
ducted at the institute (then a laboratory of the Ins~.tq LA rZY-jr4d
#p_Q tpmic Xnj
I. V. Kurchatov) in the Fall of 1956, after Kerst's report on accelerators with
beaW of the FFAG type. By that time Soviet scientists gad al-
ready acquired some experienco.in obtaining large electron currents,, An pirticular,
the nentioned laboratory had installed and then abandoned a device for the spiral-
ntorage of electrons (G. I..Budker and A. A. Haumov, CERN Symposium, 1, 76 (1456)),
by which, subsequently, circulating currents of th* order of 100 amperes iere ob-
tained. In 1957 two variants of this device were considered at the same time. The
first one consisted of tsto accelerators with spiral storage and subsequent transi-
tion of the particles to synchrotron state in comparatively narrow paths. The
second a,
-is had storage rings with constiint magnetic field and frequent external in
jection because of-the da~nping of the oscillations under the action of radiation.
The fir-at variant was more 6mobersome; the second variant contained an -element not
developed at that time, namely a 100-kilavolt7 commutator of 10 kilo-awbres with
nanosecodd fronto --At the end of 19S79 the.first,positive results were ebtaLned
