THE INFLUENCE OF DENSITY ON PLASMA BEHAVIOUR IN THE HBTX1A REVERSED FIELD PINCH
During long (up to 14 ms) constant current discharges in the HBTX1A reversed field pinch, the density falls until a plateau is reached whose value, in the neighbourhood of 2 x 10**19 m**-3, depends linearly on the current. Associated with the density decrease are increases in electron temperature T-e (up to about 400 eV), resistivity anomaly, Z*-eff, and streaming parameter, xi. The product n-eT-e (or beta-theta) remains approximately constant throughout. The Z*-eff often rises to values considerably in excess of 10, in contrast with the much lower value of effective ion charge measured spectroscopically.
