A source of soft X-ray emission based on the miniature 15 kJ (9È14 Ó) plasma focus was developed and tested. The X-ray emission was channelled along the chamber axis through an opening in the inner electrode (anode). A regime with a mean output of more than 100 J per discharge was found. At a discharge current of 280 kA and repetition rate of 3.5 Hz achieved by the device, its lifetime was estimated to be 107 commutations (about a year of continuous operation). A demonstration experiment on irradiation of an X-ray resist is discussed.
A system for measuring of absolute neutron yield and its spatial anisotropy is described. The system was developed in the LPI (Lebedev Physical Institute) and destined for study properties of neutron emission of pulse plasma installations such as Plasma Focus (PF), z-pinches and others. The system consists of transported compact activation detectors and small optically isolated neutron activation counter with 4 th digit data output to LCD display. The electronic unit is built on the TTL standard. In power supply of the system the small-size accumulators are used. : 52.58.Lq, 52.70.Nc
