METHOD OF PREPARING HIGH-DENSITY HYDROGEN ISOTOPES

摘要

applied nuclear physics. SUBSTANCE: ampoule 1 with double wall enclosing hollow 7 is placed in target 2 connected to hydrogen utilization system 3. Target 2 is evacuated to pressure 10-4 mm Hg and hydrogen isotopes (including tritium) are directed into ampoule 1 from source 4. External source 5 supplies nonradioactive hydrogen isotopes. The latter are liquefied by pumping liquid helium through heat-exchange radiator 6. Liquefied nonradioactive isotopes (primary refrigerant) are fed into hollow 7 in order to liquefy hydrogen isotopes in ampoule 1 over elements 8 and 9 connected with hollow 7. When specified amount of hydrogen isotopes is accumulated in ampoule 1, the latter is heated to achieve desired density of hydrogen isotopes. Working pressure exceeds 120 MPa and temperature exceeds 550 C. EFFECT: simplified procedure and preserved radiation safety. 1 dwg
