An impurity pellet injector is being developed for the RFX reversed field pinch (RFP) with three aims: measurement of the pitch of the magnetic field lines, transport studies, and first wall conditioning. The injector uses pneumatically accelerated m

Powder consolidation using a shock compression apparatus is a potential method for the processing of bulk materials. Two-stage gasdynamic guns take advantage of light gases properties to accelerate projectiles to hypervelocity. The prototype develope

IEEE Thirteenth Symposium on Fusion Engineering.
The most recent steps for developing injectors that meet the requirements of the Frascati Tokamak Upgrade are described. Details of a cryostat capable of building 1.6-mm-diameter deuterium pellets are given. Such pellets have been successfully accele

15th IEEE/NPSS Symposium. Fusion Engineering.
Among the different methods of pellet injection for Tokamak refueling, the two-stage gun is presently the most suitable for pellet speeds over 2000 m/s, but for continuous operation two main problems are to be solved: wear of the pistons and plasma c

[Proceedings] The 14th IEEE/NPSS Symposium Fusion Engineering.
Effects of barrel roughness on the performance of two-stage pellet injectors were studied experimentally and numerically. It was found that a 50% roughness reduction (from 0.5 to 0.25 mu m) allows a 6-8% increment of pellet speed for assigned conditi

Proceedings of 16th International Symposium on Fusion Engineering.
The two-stage light gas gun is presently the most suitable method for injecting solid deuterium pellets at velocities in excess of 2000 m/s. However, the use of this technique in plasma machines presents some drawbacks: (1) the relatively large mass

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 a two-stage light gas gun. Speeds up to 2.9 km/s have been achieved in a reliable perfor

Recent results on injection of D2 pellets, using an improved light gas gun, are reported. In order to overcome the limits imposed by the low mechanical strength of solid hydrogen, a double‐piston gun has been developed, in which the pressure pulse
