Contribution

It provides theoretical simulations of diffraction radiation for various slit systems and compares these results with experimental data from DESY, advancing non-invasive beam diagnostics.

Findings

Simulation results match experimental data

ODRI can analyze high-intensity bunches without damage

Potential for real-time beam diagnostics

Abstract

New research in acceleration physics leads to growing up the power of charged particles bunches. Existed methods based on interaction of detection devices with bunches do not satisfy our need, because of the fact that new high intensity bunches can damage this devices. Moreover, these methods do not allow analyzing the bunches in real time. Recently new technique based on ODRI (optical diffraction radiation interference) by a bunch at its propagation through the slit was proposed. In this work the results of theoretical simulations on diffraction radiation, in particular ODRI, by electrons for various slit systems as well as the comparison with the DESY experimental data are presented.
