STUDY OF NUCLEAR SEEDED MHD PLASMAS.
Abstract
The feasibility of using pulsed neutron generation and pulsed ion chamber techniques for investigation of MHD plasma generation by nuclear seeding has been studied. Experimental methods and devices developed for the generation and measurement of helium plasmas produced by the He3(n,p)T3 reaction in He3 seeded gases are described. Densities of plasmas produced with a pulsed Van de Graaff neutron source were measured by the pulsed ion chamber methods for both purified He3 and He3 - 3%CO2 gas mixtures at one atmosphere pressure. The results of first generation equilibrium, growth, and decay measurements are reported. A two-body volume recombination loss mechanism was experienced with pure He3; however, a one-body loss process was observed to be the dominant effect present for the He3-CO2 gas fillings. An enhancement in the degree of ionization was observed for the CO2 containing gas. (Author)
