(Color online) Cross sections of nuclear reactions that have potential for neutron generation using ions. Above 1 MeV the 7Li(d,xn) reaction is the highest by far. The inset shows the target setup used in this experiment, where ions accelerated from a CD2 foil are incident on a LiF slab.
(Color online) The left side shows false color traces from the TPIS of a Cu foil (top) and a CD2 foil (bottom). The right side shows the proton spectrum as measured using RCF (dotted line), as well as spectra of protons (squares) and deuterons (triangles) taken from the TPIS, which have been normalized to the RCF data (all from Shot 18).
(Color online) The main figure shows smoothed raw traces from the nTOF diagnostic on Shot 9. The darker and lighter lines are from the front (away from laser), 17.5°, and rear nTOFs, 157.5°, respectively. The lightest line shows a shot from the front nTOF taken by shooting only CD2 without a LiF converter (Shot 18). The inset shows a magnified portion of the signal, where the upper axis has been converted to neutron energy.
(Color online) Maximum neutron energies. The green triangles (Shot 9) and orange squares (Shot 4) show data with the same nominal laser parameters (i.e., 360 J, 9 ps). The lines show the (maximum) neutron energy expected through elastic interactions with varied incident deuteron energies, Ein.
Neutron fluences from experiment using CR-39 versus angle. The triangles (Shot 9) and squares (Shot 4) show data at the same nominal laser parameters (i.e., 360 J, 9 ps).
