Ultrafast Electron Cascades in X-Rays Detector

Abstract:

A new detection method based on the ultrafast refractive index change of semiconductor was used for X-rays detection. Since temporal and spatial resolutions are important parameters of the ultrafast X-rays detector, the electron cascades in gallium arsenide and cadmium selenide were studied using Monte Carlo method. According to the calculations, the energy deposition time and scale are similar in gallium arsenide and cadmium selenide at low energy region, but different at high energy region. Electron cascades don’t have much impact on getting picosecond time resolution and high spatial resolution.
