RADIAL ENERGY BALANCE ANALYSIS OF ASDEX H-MODE DISCHARGES
Radial transport and confinement properties of ELM dominated (H) and ELM free (H*) beam heated ASDEX discharges are studied using the PPPL transport analysis code TRANSP. For similar plasma parameters the H* discharges have energy confinement times of about 1.5 as large as those in H discharges and correspondingly reduced electron heat diffusivities due to the absence of the ELM's. Electron conductive losses dominate the energy losses besides radiation cooling.
