Observation of the neoclassical current in the Small Heliac Experimental Apparatus (SHEILA)
- Plasma Research Laboratory, The Australian National University, Canberra, ACT 0200 (Australia)
The first measurements of internal currents in a toroidal heliac are reported. It is suggested that the toroidal current observed in the Small Heliac Experimental Apparatus (SHEILA) [Nucl. Fusion {bold 25}, 1485 (1985)] in the low density regime consists mainly of the bootstrap current and the Pfirsch{endash}Schl{umlt u}ter current, the net toroidal component corresponding to the uni-directional bootstrap current, and the asymmetric radial profile of the observed current indicating a mixture of bootstrap current with the bi-directional Pfirsch{endash}Schl{umlt u}ter current. {copyright} {ital 1997 American Institute of Physics.}
