Self-sustained steady-state tokamak equilibria for National Spherical Torus
Experiment (NSTX) and Spherical Torus-Volume Neutron Source (ST-VNS) are p
resented. It is demonstrated that the amount of the pressure gradient drive
n current which includes the bootstrap current and the diamagnetic current
is comparable to the designed current specification in these devices. A pos
sible startup sequence by increasing plasma pressure is also illustrated. (
