Description
A non-invasive bunch length monitor based on Cherenkov diffraction radiation (ChDR) is being developed for the AWAKE Run 2c 18 MeV seeded electron beam line. The monitor consists of protruding dielectric radiators that generate polarization radiation when an electron bunch passes in close proximity to them. Coherent ChDR emitted from the radiators is measured by zero-bias Schottky detectors operating in different frequency bands, enabling a relative measurement of the RMS bunch length. In this paper, we present tests performed at The CERN Linear Electron Accelerator for Research (CLEAR) to characterize the signal and observe a possible shadowing effect due to protruding radiators.
