| Popis: | Two plasma‐focus devices at the Lawrence Livermore Laboratory, the B Division device (BDPF), with a stored energy of 73 kJ at 18 kV, and the Physics Department device (PDPF), with a stored energy of 67 kJ at 20 kV, were operated with various mixtures of D2 and He3. The purpose of the experiments was to evaluate the D‐D/D‐He3 yield ratio as a diagnostic tool for determining the plasma ion temperature. Measurements were made in the high‐pressure mode (total pressure of 4.0 Torr for the BDPF, 7.5 Torr for the PDPF), where previous measurements using carbon activation showed no significant ion acceleration to energies above the 330‐keV carbon (d,n) reaction threshold. The yield from the D(d,n)He3 reaction was determined from measurements of the total neutron yield using the standard silver‐activation technique. The yield from the He3(d,p) He4 reaction was determined by measuring the reaction‐product protons by copper activation. The Cu anode insert from the center electrode was analyzed for γ activity followi... |
