ELECTRON IRRADIATION OF MATERIALS.
Abstract
A description is presented of a 2 Mev pulsed electron facility which employs a scanning electron beam probe at the target plane for the investigation of transient trapping phenomena in irradiated materials. The application of the facility to the study of trapped charge behavior in electron irradiated dielectrics is described somewhat below the threshold for spontaneous breakdown in the materials in a selected dose rate regime. A tentative interpretation is made of the characteristic decay curves for these high resistivity materials. An outline is presented of beam diagnostic techniques suitable for the 10 to the 10th power to 10 to the 11th power w/sq cm peak power electron beams available from a 4 Mv, 20 nanosecond pulsed electron accelerator and examples of their application discussed. A preliminary evaluation is made of some of the effects produced in materials by these relativistic self-focused streams at dose rates to 10 to the 15th power rad/sec. (Author)
