Popis: | A pneumatic injector for periodic injection of fuel pellets into plasma of a thermonuclear facility in a continuous mode for an infinitely long time is described. The continuous injection is ensured by a screw extruder and two cryorefrigerators that allow extrusion of solid hydrogen rods with diameters of 2 and 2.5 mm at a speed of up to 40 mm/s in a steady-state mode. A cylindrical cutter and a valve with compressed hydrogen form solid-hydrogen pellets with diameters of 2 and 2.5 mm from the rod and inject them into plasma at a frequency of up the 11 Hz and a speed of 150–550 m/s. The reliability of the injector’s operation is 99%. |
