Space potential measurements in the central cell of TMX
- 1. Rensselaer Polytechnic Inst., Troy, NY
Description
A heavy ion beam probe has provided detailed spatial and temporal measurements of the central cell space potential (phi/sub e/). With gas box fueling of the plasma at typical feed rates (approx. 1200 atom-amps) the potential is strongly parabolic to at least 25 cm (r/sub limiter/ = 38 cm), with phi = phi/sub max/ (l - (r/32cm)2) providing a good fit and 300 < phi/sub max/ < 450 volts depending on machine conditions such as neutral beam heating current, etc. With puffer fueling the central cell potential remains relatively flat to at least 30 cm
