Scientific Programme:

   IREN. Construction of the Intense Resonance Neutron pulsed source IREN based on a linear electron accelerator (LUE-200) and a neutron multiplying assembly.
Main characteristics of the IREN source:
The LUE-200 hat electron energy - 210 MeV, mean peak current - 5 A, frequency - 150 Hz, pulse width - 0.25 µs, the and mean power - 10 kW. An electron pulse is converted into a burst of photoneutrons by a special target placed in the center of an air cooled breader.
  The beryllium-tungsten target converter in a stainless steel envelope is cooled by the He gas flow. The breeder is the subcritical plutonium core with the volume 2.5 l and the breeding coefficient 30.

  The neutronic parameters of the source are: fast neutron pulse width - 0.4 µs, mean power - 12.5 kW, peak power - 220 MW, mean neutron flux 1.0

10¹⁵ n/s, peak flux - 2.7

10¹⁹ n/s, interpulse background - 5.6%.

Expected main results in 2001:

The realization of the project IREN continues. The electron source-creation of a stand for the gun, manufacturing of the gun elements, developing of a method for the diagnostics of beam parameters. The magnetic system-designing and manufacturing of the magnetic system elements, including a power supply source and system-by-system adjustment of elements. The RF systems-reaching of the rated parameters on a full-scale stand of FLNP (60 MW, 2.5 µs and 50 Hz) in the system: accelerating section + modulator + klystron + RF-feeder + terminal load. The vacuum system-assembly and trial measurements in the volume required for a full-scale stand. The system of diagnostics, control and safety-experimental testing of induction sensors of current and waveguide sensors at LUE-40. Completion of the manufacturing of RF power multiplication system and a buncher. Assembling of the first section on a full-scale stand. Trial measurements of the auxiliary system variants of the IREN facility. Completion of the technical project of the IREN facility, including safety substantiation and approval by Russian authorities. Obtaining of a license for building the IREN facility. Preparation of the working drawings of the multiplication target. Development of technical design for IBR-30 decommissioning.
Development of new experimental methods for beam measurements at IREN.
