INVESTIGATIONS OF HIGH ENERGY DEUTERONS IN A DENSE PLASMA FOCUS DEVICE BY MEANS OF NEUTRON EMITTED IN THE 7-LI - D PROCESS
A study of the higher energy part of the deuteron spectrum produced by the Frascati 1-MJ plasma focus device is carried out through measurements of (a) the energy distribution of prompt neutrons emitted by D(d,n) and 7-Li(d,n) reactions using three time-of-flight spectrometers and (b) the total neutron fluence and the high energy neutron fluence using silver and lead activation counters, respectively. The results clearly confirm the existence of an energetic deuteron beam, E**b <= 2 to 4 >= MeV, and lower energy streams circulating in the plasma, E**2 about 100 keV, responsible for the main part of the neutron production through the D(d,n) process, with the ratio of the two components, phi**b-d/phi**s-d about 10**-4. The methodology of measurements and of data analysis described represents a definite improvement with respect to those described in previous publications.
