High-beta studies in the ISX-B tokamak

PDF Version Also Available for Download.

Description

Experimental results from the ISX-B tokamak (major radius R/sub 0/=0.93 m, minor radius a=0.26 m, plasma current I/sub p/ 230 kA, elongation k=1.1 to 1.6, toroidal field B/sub phi/ less than or equal to 1.5 T, density anti n/sub e/ less than or equal to 1.1x10/sup 20/ m/sup -3/, neutral-beam power P/sub b/ less than or equal to 2.5 MW) at volume-averaged beta (<..beta..>) values up to 2.5% are described. Two aspects of these studies are presented: (1) empirical scaling of beta and of confinement time, and (2) MHD equilibrium analysis of ISX-B plasmas. The main points which are made ... continued below

Description

Experimental results from the ISX-B tokamak (major radius R/sub 0/=0.93 m, minor radius a=0.26 m, plasma current I/sub p/ 230 kA, elongation k=1.1 to 1.6, toroidal field B/sub phi/ less than or equal to 1.5 T, density anti n/sub e/ less than or equal to 1.1x10/sup 20/ m/sup -3/, neutral-beam power P/sub b/ less than or equal to 2.5 MW) at volume-averaged beta (<..beta..>) values up to 2.5% are described. Two aspects of these studies are presented: (1) empirical scaling of beta and of confinement time, and (2) MHD equilibrium analysis of ISX-B plasmas. The main points which are made are, respectively: (1) global confinement time tau/sub E/ exhibits a strong positive dependence on plasma current (I/sub p//sup 3/2/), a negative dependence on beam power (P/sub b//sup -2/3/), little or no dependence on <..beta..> or density, and no correlation with variations in the observed (m=1;n=1 dominated) MHD activity, and (2) profile analysis is coupled with an MHD equilibrium solver to obtain a model of the plasma consistent with profile, magnetic probe, and soft x-ray data, and with the boundary conditions imposed by the poloidal coil currents.
