Experimental evidence of low frequency current drive in the Phaedrus-T tokamak.

Abstract

The first experimental evidence of low frequency current drive in a tokamak has been observed on the Phaedrus-T tokamak. The principal evidence is a fractional loop voltage drop of 0.35 that cannot be accounted for by an increase in plasma temperature, decrease in effective plasma charge, or decrease in stored magnetic energy. The estimated driven current is 20--35 kA out of a total of 64 kA.
