Abstract
The paper considers the neutron and hard X-ray (HXR) generation by plasma focus chambers operating as part of the ING-102Э subkilojoule neutron generator with a storage capacity of 4.4 μF and an amplitude of the discharge current through the chamber electrodes in the range from 100 to 200 kA. T19-L316 type chamber was used. which ensures the neutron yield with an energy of 2.5 MeV at a level of 105–107 neutrons/pulse. Measurement of the neutron level yield and HXR of the T19-L316 chamber was carried out, the presence of operating modes with the generation of HXR without neutron radiation with deuterium filling of the chamber is shown. The neutron pulses duration of the T19-L316chamber was determined, and the dependence of the duration on the neutron yield level and on the composition of the working gas in the PF chamber was studied. The PF chamber operation in the regime wihout neutrons was experimentally confirmed when the chamber volume was filled with hydrogen, and a comparison was made of the level of the HXR yield when working with hydrogen, deuterium, and deuterium with an admixture of argon. Also, a T19-L316chamber design for neutron generation with a 100-fold reduced HXR yield, implemented is proposed.
