Abstract

Characteristics of plasmas in Tokapole II (a noncircular poloidal divertor tokamak) with directly measured q as low as 0.4 are discussed. This is a q regime bounded by well studied q>1 tokamaks and q0.1 reversed-field pinches. After q drops below 1, soft-x-ray sawtooth oscillations begin. During the oscillations the central q values remain stationary and below 1, while a small oscillation in the edge q values near q=1 is observed.
