Detection of Electron Radiation Pulses Generated by a Subnanosecond Accelerator

摘要

The characteristics of the electron beam generated by a subnanosecond accelerator with double sharpening in the voltage-pulse shaping circuit have been recorded. The duration of the electron-beam current pulse was 240-270 ps, the current amplitude was approximately 1.5 kA, and the maximum electron energy was approximately 0.95 MeV. The pulse-response characteristics of SPPD29k and SPPD29-02 X-ray semiconductor detectors were determined: their full widths at the half-maximum tau(0.5) were approximately 320 +/- 30 and 450 +/- 30 ps, respectively.
