SECONDARY ELECTRON YIELD VS PRIMARY ENERGY FOR COMMERCIAL COATED-GLASS RESISTANCE STRIPS

The mean secondary electron yield has been determined as a function of primary electron energy from 20 to 70 eV for the dynode-strip surface of a commerical resistance-strip magnetic electron multiplier. Both the primary energy and the secondary yield were determined by measuring the multiplier output current while varying the voltage applied to the field-strip input end at each of three fixed dynode-strip input-end voltages. The measured mean secondary yield increases linearly from about 1.2 at 20 eV to about 1.7 at 70 eV. © 1969 The American Institute of Physics.
