  We present the results of the commissioning of the pulsed linear electron accelerator with beam energy of 10 MeV, developed with the participation of scientists and engineers of the SINP MSU, LEA MSU Ltd. and JSC "RPE "Toriy". The source of RF power for accelerator is a multibeam klystron KIU-147A operating at 2856 MHz with pulse output power 6 MW and an average power of 25 kW. As a result of commissioning we received at the output of accelerator scanning system an electron beam with an energy of 10 MeV and an average power of more than 15 kW. Capture ratio and electronic efficiency of 1.24 m long accelerating structure are greater than 65%.

  Several variants of a low-energy storage ring for Thomson scattering X-ray source were considered in *. The most promising variant "C" of the ring with small dimensions and large dynamic aperture has also large momentum compaction factor, which would lead to too long bunches with RF cavity operating at 714 MHz, so shorter wavelength must be used. In this paper we present results of optimization of S-band double-cells cavity with parasitic mode damping by chokes similar to **. Interaction of the bunch circulating in the ring with cavity parasitic modes is simulated.
