MEASUREMENTS OF SECONDARY ELECTRON EMISSIONS IN KCl AND KBr (in German)
Measurements of the secondary electron emission in KCl and KBr single crystals and in a KCl vapor-deposited layer were made by the single-pulse method. The yield values measured were compared with the dependence of the yield on the temperature resulting from the Dekker theory. At higher energies E/sub p/ of the primary electrons sigma decreases with increasing temperatures between room ternperature and 300 deg C; it is almost inversely proportional to the root of the absolute temperature. At small primary energies the yield is temperature dependent. The energy distribution of the secondary electrons depends on the primary energy; the number of electrons with low energy increases with the primary energy in proportion to the number of superfluous electrons.
