| Popis: | Nowadays laser wakefield acceleration (LWFA) is considered as one a perspective method for GeV electron beam production. Combination of laser accelerated electrons and Compton backscattering of probe light beam opens possibility to create the table top source of femtosecond light beam in x-ray and gamma range. Project of laser-driven Compton light source started in ILP SB RAS in collaboration with BINP SB RAS. Production of 1-10 pC electron beams sub-ps time range duration with energies up to 100 MeV is expected as a result of the first stage of the project. Since energy of electrons does not exceed of 100 MeV, it allows using Faraday cup (FC) with reasonable dimensions, instead of commonly used integrating current transformer (ICT). Geometry of FC was optimized taking into account of beam stopping simulation as well as low capacity requirement. RF properties, simulation of the system operation were carried out. System has been tested at the VEPP-5 electron linac. Results of development and testing of this FC are presented.
