Temporal Deuteron Current Determinations Using Neutron Time-of-Flight.
Abstract
In experiments conducted on the NRL Gamble II device, focused-ion currents have previously been inferred by combining time-integrated neutron yield data with time-resolved diode electrical characteristics in a model for ion production. The time variation of ion current can be determined in a more direct fashion from neutron time-of-flight measurements at various angles to the beam direction. Such measurements have recently been successfully carried out in the hard x-ray environment of Gamble II by employing fast-recovery scintillator-photomultiplier detectors. Measurements of the deuteron energy and emission time deduced from neutron time-of-flight are consistent with current understanding of the ion generation process. The ion current vs. time is unfolded from measured neutron signals by combining them with the temporally-resolved diode voltage and neutron-production cross sections. (Author)
