Description
Charged particles traveling nearby a dielectric material at velocities greater than the speed of light in the medium emit Cherenkov Diffraction Radiation (ChDR). This effect is an interesting candidate for non-invasive longitudinal beam diagnostics due to remarkable characteristics such as a large and narrow emission angle as well as high sensitivity to bunch profile and position. Despite the many experimental observations of this radiation, theoretical models remain inconsistent, and their predictions vary in orders of magnitude. An experimental campaign ongoing at ATF2 aims at an absolute measurement of the incoherent light yield in the visible range. This contribution presents the latest developments of the experimental apparatus, recent results and a discussion on further improvements of the setup.
