Since 1985 a collaboration between the Frascati and Milano Groups has been operating and has been aimed to the realization of a solid D2 pellet injector based on two-stage light gas gun. Speeds up to 2.9 km/s have been achieved in a reliable performance with unbroken pellets. In this paper a miniaturized version of the injector, to be operated on the Frascati Tokamak, FTU, will be described. Furthermore, developments aimed to obtain the injection of many pellets in rapid succession, still using a two-stage gun, have been initiated and will be described.

Abstract
Since 1985 a collaboration between the Frascati and Milano Groups has been operating and has been aimed to the realization of a solid D2 pellet injector based on two-stage light gas gun. Speeds up to 2.9 km/s have been achieved in a reliable performance with unbroken pellets. In this paper a miniaturized version of the injector, to be operated on the Frascati Tokamak, FTU, will be described. Furthermore, developments aimed to obtain the injection of many pellets in rapid succession, still using a two-stage gun, have been initiated and will be described.File in questo prodotto:
