Description
Beam loss monitors based on optical fibers are widely used at GeV-scale accelerators [1]. Recently there was proposed to use such a technique for a beam profile diagnostics [2]. We have investigated a feasibility to use the Cherenkov radiation (ChR) generated in a fiber to measure a beam divergence. Measurements were carried out for different angles between a fiber axis and the electron beam and showed a possibility of such kind of diagnostics. The decay of ChR in a fiber with thickness 0.6 mm and length up to 10 m were measured. The proposed technique can be used for low intensity beams (a few pC level).
