Tritium Handling and the Preparation of DT-Containing Micro-Targets for Laser Fusion Experiments

  • Dean H. W. Carstens


Within the High-Temperature Chemistry Group (CMB-3) at Los Alamos Scientific Laboratory hollow micro-targets for fusion experiments are routinely filled with 50–50 DT gas at pressures ranging from 1 to 1000 atm and temperatures of 300–400°C. Li(D,T) targets are also prepared using the exchange of LiD spheres with tritium gas. The gas system has provisions for mixing, purifying (using a uranium-tritide bed), storing, and analyzing (using mass spectrometry) mixtures of DT gas. Although only small amounts of gas are actually used in the filling procedure, the system is capable of handling up to about four moles (90l) total. The highpressure gas is generated using a metal hydride bed which produces the pressure via the decomposition of V(D,T)2. The pump is considerably more convenient to use than conventional systems and is capable of pumping pressures of up to 1400 atm (20,000 psi). Problems and safety aspects of handling and containing bulk amounts of tritium are discussed.
