Central helium density measurements in PLT
The central helium density in PLT has been deduced from measurements of the ratio of d-/sup 3/He to d-d fusion reactions during deuterium neutral beam injection. The inward transport time for /sup 3/He puffed at the edge plasma was 10 ..-->.. 30 msec. The decay time of the central /sup 3/He density increased with electron density, varying from 0.3 sec to greater than 1.0 sec over the density range of (1 ..-->.. 5) x 10/sup 13/ cm/sup -3/.
