The injector is a pneumatic type 10-barrel system for injection of frozen hydrogen or deuterium pellets into plasmas. All the barrels can operate independently. Every barrel has an own helium heat exchanger, a fast valve for propellant gas admission and a gate valve for the pellet production. This technique provides a continuous steady -state pellet formation and injection of an unlimited amount of pellets.
Cryogenic system is a helium flowing cryostat.
