AN OVERVIEW OF PBX-M H-MODE RESULTS

The PBX-M tokamak has an array of unique features that allow it to stu dy regimes of enhanced confinement and stability. In particular, becau se of its divertor operation, PBX-M has proved to be a valuable contri butor to identifying and understanding various features of H-mode phys ics. To be reported here are recent results of H-mode studies of m=1 b ias induced H-modes, L- to H-transitions, including suppression of tur bulent transport, ELMs and other related energy loss mechanisms, and I on Bernstein Wave modification of H-mode discharges.
