| Abstract | The existing techniques for gamma beam diagnostics at medical accelerators based on X-ray films have several disadvantages such as insufficient spatial resolution, difficult realization and off-line mode. In the works*,** a feasibility of Cherenkov radiation (CR) in glass fibers for charged particle beam diagnostics was demonstrated. An application of glass fibers scanning for gamma beam diagnostics may have a lot advantages including a possibility of on-line measurements. For this goal we used optical fiber with 0.6 mm diameter and length up to 10 m. An efficiency of CR generation in such fibers and signal attenuation in a long fiber were investigated using the Tomsk microtron electron beam. The shape of gamma beam field produced by the medical SL-75-5MT 6 MeV electron accelerator was measured using the proposed technique. It is shown there it is possible to measure not only gamma beam spatial distribution, but also its angular distribution. | |||||
