A supersonic gas injection system for fueling and probing fusion plasmas

Collis, S; Howard, John; Blackwell, Boyd; Carlsson, Peter; Abelsson, Mattias; Powell, B


The large gas reservoir surrounding the H-1NF plasma leads to difficulties in achieving the density control required to maximize the plasma temperature. We have designed and tested an alternative fuelling system which uses a double conical nozzle to generate a directed flow of particles into the plasma without adding to the gas inventory in the rest of the vacuum vessel. By using a closed plenum at a programmable pressure and a piezo-electric valve, the particle flux can be dynamically changed...[Show more]
