Compact activation detectors for measuring of neutron emission on Plasma Focus installations

摘要

The paper presents the two compact simple systems for the measurement of the absolute neutron yield in the range 10⁶ –10¹² neutrons/pulse and higher and spatial anisotropy of neutron radiation. The systems are destined for the registration of the short duration neutron radiation of the pulsed plasma installations, such as Plasma Focus (PF), z-pinches and others plasma installations. This paper also includes the results of the neutron emission measurements on different PF installations: "Tulip" (P.N. Lebedev Physical Institute, Moscow, Russia), the PF–1000 and PF–150 installations (Institute of Plasma Physics and Laser Microfusion, Warsaw, Poland).
