Parametric Channeling Radiation and its Application to the Measurement of Electron Beam Energy

Abstract

We have proposed a method for observing parametric channeling radiation (PCR) and of applying it to the measurement of electron beam energy. The PCR process occurs if the energy of the channeling radiation coincides with the energy of the parametric X‐ray radiation (PXR). The PCR process can be regarded as the diffraction of “virtual channeling radiation”. We developed a scheme for beam energy measurement and designed an experimental setup. We also estimated the beam parameters, and calculated the angular distributions of PXR and PCR. These considerations indicate that the observation of PCR is promising.
