D(d,n) neutrons induced by ions from explosive evaporation of Ta anode deuterium occluded. X-ray mode of plasma focus discharges

Summary form only given. Neutron yield, Y/sub n/=10/sup 7/-10/sup 8/ was observed when PF at SRRC (Filippov-type; 0.3 Torr of Ar; 50 kJ; 12 kV) was fired in the X-ray mode. Before the experiment, the Ta anode was immersed in D/sub 2/ and due to occlusion, the atomic ratio 2(Ta):1(D) was obtained. Af...

Zusammenfassung:Summary form only given. Neutron yield, Y/sub n/=10/sup 7/-10/sup 8/ was observed when PF at SRRC (Filippov-type; 0.3 Torr of Ar; 50 kJ; 12 kV) was fired in the X-ray mode. Before the experiment, the Ta anode was immersed in D/sub 2/ and due to occlusion, the atomic ratio 2(Ta):1(D) was obtained. After a few shots in pure Ar, neutrons do appear and hold their yield during the entire experiment. Y/sub n/ was detected with Ag-activation counters (end-off; 0/spl deg/) and Time-of-Flight, ToF, [X(E/sub x//spl ges/0.2 MeV) and n(E/sub n/=2.45 MeV)] was measured with fast plastic detectors (/spl les/2 ns), behind collimators aimed for the chamber roof (side-off; 90/spl deg/) and Pb-shield (5 cm). Ion energy, E/sub D+/, was defined from measured delay, T, between X and n signals to be: T=ToF(D/sup +/)+ToF(n)-ToF(X) Experiments were done for different combinations of ion bases and neutron bases.
