Design of a PXR experiment based on the NCEL

【摘要】 Parametric X-ray Radiation(PXR) can be used as a novel,quasi-monochromatic energy-tunable and high-yield X-ray source.It is produced at the Bragg angle by a relativistic electron beam passing through the periodic structure of crystal materials.This article concerns the PXR experiment using low energy electrons(10 MeV) from NCEL(Novel Compact Electron-Linac).The difficulty of the experiment is to distinguish the PXR photons form the background.The design of the experiment relies mainly on the yield of PXR,the Bremsstrahlung background of the X-rays and the capability of the detector.更多还原
