Comparison of the Numerical Model with Experimental Data for a Beam-Loss Monitor Based on an Optical Fiber

—The principle of operation of a distributed beam-loss monitor based on Cherenkov radiation in an optical fiber is considered. This device makes it possible to obtain a real-time distribution of losses across the entire accelerator. A numerical model of the monitor describing its spatial resolution is developed for various scenarios of the beam losses. Ways to improve the monitor are considered. It is shown that the simulation results are in good agreement with the experimental data obtained on the e – e + injection complex at the Budker Institute of Nuclear Physics.
