Optimizing of Experimental Load of PFZ-200 Plasma Focus

Popis výsledku v původním jazyce

This article presents a study of neutron emission on the PFZ-200 plasma focus at the Department of physics on FEE CTU in Prague, Czech Republic. In order to achieve the highest and most stable neutron yields, the deuterium working gas pressure and the anode shape were systematically varied. We observed the plasma time to the pinch and the discharge current by the Rogowski coil and neutron emission by the silver activation detector and scintillation time-of-flight detectors. The imploded plasma was visualized using a fast X-ray pinhole camera with a gated microchannel plate detector. The experiment presents the z-pinch discharges with the current maximum above 200 kA and the average neutron yields of 3x10^8 neutrons/shot. Measured pinch times were in the range from 1.65 to 1.85 μs . The hollow round anode configuration performed the most stable neutron yields with a deviation under 20%.
