IMPURITY PELLET INJECTOR ACCOMPANIED BY SOLID HYDROGEN ISOTOPE SHELL FOR FUSION DEVICE

摘要

PROBLEM TO BE SOLVED: To raise reliability of formation and discharge of an impurity pellet to be made a capsule of solid hydrogen isotope shell and simplify in design. SOLUTION: The impurity pellet injector accompanied by solid hydrogen isotope shell contains a vacuum chamber 1 containing an injector barrel, a mold 2 of shell where a cavity is connected to the cavity of the injector barrel, a cooling system 3 for the shell mold, a holder 5 of the impurity pellet connected to the shell mold, a pusher 7 installed in the holder and being capable of moving the pellet from the holder into the cavity of the shell mold at the end, a gas supply system 8 connected to the shell mold and the cavities of the injector barrel and of the holder of the pellet, a vacuum pump system 9 for forming a vacuum in the vacuum chamber, the injector barrel, the holder and the shell mold, and a driver 10 for the impurity pellet pusher which is connected to the pusher outside the vacuum chamber.
