TEXT: Tests were made with SiO2- and NaCl-based mixturas containing hun-
dredths and tenths of a percent of In, Tl, Ga, Ge, As, Cd, Te, Sn, Pb, and Zn,
as well as 1.5 % of Cu in the form-of oxides and sulfides. Weighed 20 mg samples
were placed in the channel of the bottom carbon are electrode and ignited until
total evaporation of impurities. AVIGn-22 'ISP-22) spectrograph was used. Upon
increase of the channel depth from 2 to 6 mm, the "idle" burning time of the are
noticeably increases, but the evaporation time of tho elements changes little.
The evaporation time dropped by 3 - 5 times when the bottom electrode was cooled

temperature of'the electrodes increases rapidly for 20 - 40 see. at all point's
at a constant distance from the discharge until it reaches a constant value,
irrespectively of the samp'Le'3 composition. The temporature attained by the
electrode depends most of all on the ionization potentials of the elements enter-
Ing the discharge and on the power of the are; the sample's boiling point Is of
secondary importance. The heating-up rate and temperature of the electrodes in-
crease considerably with increasing current intensity. The temperature of the
top electrode does not depend on the nature of the substance introduced into the
bottom electrode. A series of empirical formulae were proposed for describing
these regularities. The dependence of the intensity of the lines I on the cu,,rent
intensity I was examined at 5 - 20 amps. It was found that I = ik, where .4c .
1.3 - 1.555. It is supposed that the increase of I with the growth of i is,due
to the observed widening of the discharge column. It was found that at a 8orstant
exposure time the constant back4g-ound intensifies with growing i at the same r%te
as 1. However, at large i values considerable reduction of the exposure time is
possible. By using this effect the sensitivity may be increased by several times.

ABSTRACT: Maxson et al (Ref.2) have described a method of using
Allen's multiplier together with an electrostatic spherical
analyser of slow ions. A disadvantage of this method is
that the electrode at which the ion beam is transformed into
an electron beam is outside the multiplier and therefore
electron collection is difficult and some losses are possible.
In the present work a new axially symmetric electron mul-
tiplier is described which was specially designed for work
in conjunction with an electrostatic spherical analyser of
low energy ions. The construction of the analyser is shown
in Fig.l. The electrodes of the multiplier are in the form
of surfaces of revolution obtained by rotation of the con-
tours of the electrodes in Allen's multiplier about the
axis 00, 1 The electron-optical arrangement was checked
using a model and an electrolitic tank. The possibility of

the efficiency is about 100% at the threshold of the dis-

ABSTRACTi It Is sometimes necessary in nuclear studies to record
ions having a small range in a material in the presence of an
intense background of scattered quanta and high energy Ions.
In such cases, it is difficult to use ordinary single-channel
electron multipliers since the pulse heights due to slow ions
and the scattered-radiations are comparable. It is not always
possible to discriminate against the backgrqund withput an ap-
preciable loss in the slow ion counting efficiency. th such
cases,,,it ip ppssible to use a two7channel electron multiplier
with a plane cathode (Ref.1). The present paper describes the
construction and some characteristics of such multipliers.
Each channel consists of 15 stages and an anode. The form and
position of the stages is similar to that described by Allen
(Ref-2). The form of the cathode is surh as to focus the elec-
trons from both of its sides onto the first stages. Correspond-
ing stages in the two channels are electrically

function of interstage voltage. Curves 1 and 2 are for a single-
channel multiplier and Curve 3 for the present two-channel
device working with a coincidence circuit. It can 'be seen that
Curve 3 reaches a plateau at inter-stage potential greater than
300 V. y-ray detection efficiency (Co 0) in the latter case is
about 10-5 while a-particle detection efficiency is about unity
(cathode: aluminum foil ? 4 thick). The proton counting
efficiency (cathode: aluminum foil 0.145 ME/cm ) was found to
be about unity above 65 keV for the two-channel instrument
working with a coincidence circuit. M.K. Listov and,11.V.Kiselev
prepared the multipliers.

focussing electrode being added. The geometry of the stages
is the same as in 8Ref.l. After activation, the overall
efficiency was 10 with the inter-electrode potential at 400 V.
Special precautions were taken to screen the first few dynodes
from external fields. The cathodes were earthed and the
anodes were at a positive potential. The efficiency for
a-part icle detection was found to be a MY% when the inter-
stage voltage was greater than 270 V. When a-particle detection
efficielicy was 100%,.the -ray detection efficiency was about
6 X 10-1) i.e. 300 t3mes less than in Allen's multiplier.

ABSTMICT: In order to obtain experimental material relating to Cranborg's theory
7of high vacuum breakdown (L.Cranberg,J.Appl.Phys.1952,No.5,1952), the behavior of
.minute metallic particles between plane electrodes in vacuo was observed. Particles
. of carbonyl iron and molybdenum about 10-4 cm in diameter were employed, as well as,
~larger particles (10-3 to 10-2 cm) of brass. The smallest particles were drawn into;
:the interelectrode region through an opening in one of the electrodes by means of
an auxiliary electric field; the larger particles were introduced mechanically. The;---
electrodes were of copper and aluminum, their gap was adjustable up to 1 am, and a
pressure of
10-5 mm Hg was maintained between them. Potentials up to 25 W were ap-*,
.plied. Charged particles (ions or electrons) originating on one electrode were re-

lated from the experimental field strengths of 10 to 4 x 104 V/cm to fields of the:
order of 105 to 106 V/cM (where vacuum breakdown occurs) , it may be concluded that
t1le 10 -4 cm'particles.would produce more than 105 to 106 ions and electrons per di&
charge at these higher fields. It is suggested th:t the production of thGse elec-
'Itrons and ions is due to.the presence of adsorbed gas an the electrodes. Orig.art.
