TITLE: Secondary electron emission of multi-alkali photocathodes
SOURCE: Radiotekhnika i elektronika, v. 10, no. 3, 1965, 484-490
TOPIC TAGS. photocathode, secondary emission
ABSTRACT: The results are reported of an experimental investigation of the
secondary emission from [Cs] Na2 KSb cathodes having an integral photo-
sensitivity of 100-200 oa/lum; the pressure during the measurements was about
10-8 torr. High values (Z0 to 36) of the secondary- emission ratio (SER) were
observed at room temperature and at a primary -electron maximum energy of
1. 5-Z kev. Plots of SER vs. primary -electron energy (for thin and thick active
ilayers) and v9. ambient temperature (- 190 +360K) are presented. It is found that
the multi-alkali cathodes have a great depth of emergence of secondary electrons;

TITLEt Inelastic Electron Reflection%nd Secondary Electron
Emission an Activated CuAlMg Alloy in the Region of
Frimary Electron Energies of From 0.5 to 20 kev
PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 6, pp. 1328-1332
TEXT: A parallel investigation of the secondary emission properties
and the inelastic electron reflection from dielectric films fastened
on to a metal base makes it possible to estimate the effective emission
depth of secondary electrons. The activated CuAlMg had a surface film of
MgO, produced in consequence of the diffusion of magnesium and heating
in an oxidizing medium. By varying the temperature and the duration of
heating films of various thicknesses were obtained. On such samples the
authors measured the coefficient of secondary electron emission a and the
coefficient of the inelastic electron reflection I by employing a static
method at 3500C. The experiments were carried out in a quasi-spherical
condenser with a high-voltage electron gun and an antidynatron grid.

Fig. I shows the results of d- and 11-measurements. dmax amounted to
13, at 20 kev d was 2.3. The I-value between 15 and 16% was character-
istic of the MgO-layer. At EP . 20 kev the curves for activated and
non-activated samples had a very similar course, % being = 30%. An
estimation of the emission depth of the inelastically reflected elec-
trons (which was equal to half the range of the electrons), shows good
agreement with the results obtained by other authors. For the thickness
of the MgO-layer one obtains 500 to 600 A. The results obtained by
experiments carried out with different film thicknesses (activation
between 1 min and 1 hour) are discussed in the following. Fig. 2 shows
the functions d(Ep) and -I(EP) for 4 films of different thickness. The
dmax of all samples was about 10 to 13. With the duration of activation
E*increases from 1-3 to 4.3 kev, i.e., film thickness increases (if the
p
effective range of the electrons in MgO equals the double film thickness,

This research examines the effect of the Mg content and of a third component,
such as rare-earth elements, on the activation and secondary ernissic -. c.;' an
Al-'Mg alloy. First, effective emitters (Clin"aX = 9 to 12) were prepared from
Al-A,rg alloys containing 0. 15% min Mg by activation in oxygen at 450-470'C Md
10-1 mm Hg for I to 4 hrs. Then, Al-Mg alloys containing 0. 003 to 0. 05% Mg
plus La or Nd were activated to show the effect of the third component on emitter
formation. Alloys containing 0. 5 to 67o La and >0. W!o Mg proved to be as good
emitters as alloys containing up to 25,16 111g. Effective emitters were also ob-
tained with the addition of Nd to alloys containing 0. 02 to 0. 04% Mg. It is assumed
that La or Nd tends to increase the rate of Mg diffusion, which in turn leads to
selective Mg oxidation on the surface. The third component can be used as an
additional control of the diffusion-oxidation processes. which lead to the formation
of an effective secondary emitter on the surface of the alloy. [EW

ABSTRACT: q uldies or long-term measurements ror weather fore-
casting have boon conducted mainly in Germany, United States, Rus-
sia, and Great Britain. Long term forecasting is much more dif-
ficult in Central Europe than it is in tropical and subtropical
climates. Succesaful forecasting must ba based on statistical e-
valuation of moasured data and a satisfactory interpretation of
these data based on physics. The forecasting should forn a special
branch of meteorology, somewhat between synoptics and climatology,
The forecasting should be based mainly on the study of the influen-
ces of the sun; although the sun constant changes only within 2.2%.
and monthly changes amount to 0.2 - 0.5%, they are important enough
to cause substantial circulation anomalies. Ultraviolet radiation
is very important in this respect. Influence of sun spots upon the
weather in Central Europe in the last 200 years is discussed. The
