Summary
Nuclear activation techniques were used to measure the fluence of high energy deuterons in a plasma focus device having a stored energy of 75 kilojoules at 18 kV. The 12C(d,n)13N (330 keV threshold) and 27Al(d,p)28Al reactions were used to provide both an absolute number of high energy deuterons and an average energy, evaluated from the 13N/28Al ratio calculated for various energies by Young. Previous measurements indicated more than 1015 deuterons could be accelerated to energies above 330 keV in the low pressure mode of operation, with a highly anisotropic distribution. Present measurements show that more than 1012 deuterons achieve energies greater than 5 MeV on some high intensity shots in the low pressure mode. The presence of multi-MeV deuterons in the plasma focus device was substantiated by measuring activation as a function of depth in 1 mil Al foils, and by measurements of neutron energy using time-of-flight.
