Attainment of quasi steady-state H-mode plasmas in the DIII-D tokamak
Description
We report the results of experiments on DIII-D where quasi steady-state H-mode plasmas with low amplitude Edge Localized Modes (ELMs) were maintained for 5 seconds. Within one second from the onset of the H-mode, most plasma parameters reach their asymptotic values (ne∼7.1013, τE≅100 ms, Zeff = 1.7) and the electron density and temperature profiles are no longer evolving. By this time, frequent ELMs and effective helium wall conditioning limit the rate of increase of ne (<10% of the beam fueling rate) and maintain the total power from impurities at a constant level.
