Temperature Effect on the Effective Secondary Emission Coefficient for He and Ne Gases

Abstract

The relation between the effective secondary emission coefficient (ESEC) ï§ and
temperature has been studied for He and Ne atoms. So we are studied the variation of ï§ with
reduced electric field to the gas pressure E p between electrodes at different temperature (T )
for each gas. It has been found that the ESEC increase with ( E p ) at constant (T ) and
decreases with temperature at constant ( E ).
