  It announces the startup of the second accelerating section of the LUE-200 electron linac of the pulsed resonance neutrons source (IREN)of the Laboratory of Neutron Physics. The block diagram, klystron and modulator parameters are presented. As a result of optimization of the accelerating system and focusing system the electron beam implemented to target. The basic parameters of the beam are measured: beam current, energy, and the energy spectrum of the beam.

  In the report works on upgrade of RF system of the LUE-200 (IREN) electron linac are provided. The main attention is paid to system of preliminary excitement of klystrons. After work on installation of the second accelerating section RF system of Installation it was considerably remade that allowed to carry out start-up of the second stage of the IREN installation successfully. Methods, features and problems in case of a training of two accelerating sections are discussed. Influence of the temperature and frequency modes on joint operation of accelerating sections. Results of setup of the RF system and a training of sections, and also results of posting of a bunch are given.

  The control system of LUE-200 an intensive pulse source of resonant neutrons (IREN) is described. The architecture of a control system and equipment structure is shown. Control system construction bases on the maximum use of instrumentation and the software for industrial systems. The control system solves following problems: set and t control of parameters of the basic systems of the accelerator (modulators, the RF-systems, focusing elements, the synchronizer, vacuum system etc.) with display of these parameters; beam diagnostics (a beam current, a profile and a beam position, energy etc.); protection of elements of the accelerator at an exit of their parameters from a working range; creation of a database of operating regimes of the accelerator; monitoring radiation level and the organization of lockup.
