Abstract:

The neutron energy spectrum 4 Torr deuterium was determined from 30 m flight histograms. An average energy of approximately 125 keV of the neutron producing deuterons within an assumed cone angle approximately 40 degrees along the z-axis was calculated by means of the target beam model. Substantial neutron production extends more than 10 cm beyond the 1 cm long focus and propagates with a 3 to 5 x 10 to the 8th cms velocity corresponding to a greater than 100 keV ion energy. Time of flight analysis confirms an ion spectrum extending from less than 70 to greater than 400 keV. The electron spectrum in 8 Torr hydrogen was derived from the hard X-radiation and agrees with the ions for energies greater than 150 keV.
