PULSED ELECTRON-BEAM HEATING
Abstract
A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time tau is proportional to d squared, where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate which was employed, if d = 1 micrometer, tau less than 1 microsecond is predicted.
