[en] Experiments on the Oak Ridge Tokamak (ORMAK) have demonstrated ion and electron heating and improvements in anti β/sub T/, anti n/sub e/, and q(a/sub l/) with neutral beam injection. They have also emphasized the need for low impurity levels in injected plasmas and the advantages of co- as opposed to counterinjection. These results, together with the favorable confinement and impurity results obtained in the Impurity Study Experiment (ISX-A) are encouraging in terms of injection-dominated, high beta experiments planned for ISX-B. This device will use 3.0 MW of injection power to study beta limits, confinement, heating, and impurity control in noncircular cross-section plasmas
