  The IREN facility (Intense Resonance Neutron Source) is now been tested and upgraded in JINR. The linear electron accelerator LUE-200 is used to generate intense fluxes of resonant photo-neutrons. Linac should deliver up to 200 MeV electron beam with 1 A or more current in 100 - 200 ns pulses. It consists of electron source, LEBT including buncher and two main accelerating sections (only one is installed up to now). Test operations shows that beam loading sufficiently influences the output beam parameters and beam energy after first section decreases from planned 55-60 MeV to 35 MeV. The buncher doesn't provide an efficient beam bunching also and beam recapturing by main section due to this is very low. Dynamics of the electron beam for traveling wave S-band linac LUE-200 was studied by numerical simulations. In report results of beam dynamics simulation and optimization taking into account beam loading discuss, parameters for new more effective buncher presents and first results of such buncher development shows.

  Joint team of CORAD and MEPhI developed a new industrial accelerating structure for average beam power up to 20 kW and energy range from 7.5 to 10 MeV. The use of modern methods and codes for beam dynamics simulation, raised coupling coefficient and group velocity of SW biperiodic accelerating structure allowed to reach high pulse power utilization and obtain high efficiency. Gentle buncher provides high capturing coefficient and narrow energy spectrum. The first linear accelerator with this structure was constructed and tested in collaboration with the company EB Tech.
