PGN,plasma neutron source

The description of the design and results of start up of the plasma generator with Matter-type electrodes reffered to as a neutran source are presented. It consists of a capacitive energy storage, the chamber with electrode set, vacuum system, of the chamber, and a supporting frame. Generator is designed in the form of a cylinder. The basic dimensions of the generator are 1500x1200 mm. The inner electrode diameter was varied from 20 to 25 mm, the distance between electrodes from 12,5 to 15 mm and the electrode length from 86 to 100 mm. Plasma generator was operated at energies of 1,5-3.5 kJ (25-40 kV) with a lifetime af 1.4 μs. The obtained neutron yield was 2x107-6x108 n/pulse obtained at 4O kV. The generator is intended for studying radiation effects in reactor materials
