INJECTOR OF DOPING MACROPARTICLES IN SOLID HYDROGEN ISOTOPE SHELLS FOR THE RMONUCLEAR PLANTS Russian patent published in 2004 - IPC

FIELD: thermonuclear plants. SUBSTANCE: injector has vacuum chamber, injector cylinder, shell generator whose space communicates with injector cylinder space, and shell generator cooling system. Casing is designed to hold doping macroparticles and communicates with shell generator. Pusher is installed in casing for moving macroparticles by its butt end from casing to shell generator space. Gas feeding system communicates with shell generator, injector cylinder, and casing spaces. Evacuating system is used to degas vacuum chamber and to generate shells. Pusher actuator is connected to pusher outside of vacuum chamber. Pusher is provided with internal passage communicating with mentioned pusher butt-end to form inlet hole therein whose diameter is smaller than size of doping macroparticle. Outlet hole of passage is provided between mentioned butt-end of pusher and its actuator. Evacuating system communicates in addition through outlet hole of pusher with mentioned passage. EFFECT: enhanced reliability of generation and injection of doping macroparticles in solid hydrogen isotope shells. 1 cl, 2 dwg
