Bc. Zhang et al., OBSERVATION OF THE NEOCLASSICAL CURRENT IN THE SMALL HELIAC EXPERIMENTAL APPARATUS (SHEILA), Physics of plasmas, 4(11), 1997, pp. 3986-3991
The first measurements of internal currents in a toroidal heliac are r
eported. It is suggested that the toroidal current observed in the Sma
ll Heliac Experimental Apparatus (SHEILA) [Nucl. Fusion 25, 1485 (1985
)] in the low density regime consists mainly of the bootstrap current
and the Pfirsch-Schluter current, the net toroidal component correspon
ding to the uni-directional bootstrap current, and the asymmetric radi
al profile of the observed current indicating a mixture of bootstrap c
urrent with the bi-directional Pfirsch-Schluter current. (C) 1997 Amer
