Description
The X-radiation from relativistic channelled electrons at the Bragg angles – Parametric X-Radiation at Channeling (PXRC) – is studied both experimentally and theoretically.
The experiment was carried out using a 255 MeV electron beam from a linac at newly constructed beam line for the study of interactions between a relativistic electron beam and crystals at the SAGA Light Source. The observed asymmetry of PXRC angular distribution at (220) planar channelling in a 20 µm Si is explained taking account of two quantum effects: initial population and transverse form-factor of quantum states of planar channelled electrons. Further perspectives for PXRC studies at SAGA-LS are analyzed.
