THERMOELASTIC STRESS PULSES RESULTING FROM PULSED ELECTRON BEAMS

Abstract
Measurements of the elastic stress pulses induced by the absorption of intense 2‐MeV electron pulses in disks of quartz,sapphire,silicon, and an aluminum alloy are reported. The relative stress amplitudes and pulse durations agree with those predicted from the thermoelastic characteristics of the absorbers and the properties of the electron pulse.
