Abstract
High poloidal beta plasmas with a correspondingly high bootstrap fract ion of 70 +/- 15% have been produced using ion cyclotron resonance hea ting, in an ELM free H mode confinement regime. This regime is termina ted by a large edge instability, causing a reversion to L mode confine ment. Possible causes for this instability am discussed and the overal l implications of the results for steady state bootstrap dominated ope ration are examined.
