Simulation of Radiation Cooling Effects in the GAMMA 10 West End-Cell Using Fluid Model

We have started a simulation study of background plasma in the GAMMA 10 west end-cell using fluid-code in order to understand divertor simulation experiment. This fluid code is B2 code without including the effects of drifts and currents. In this paper, we obtained the effects of additional neutral particles density. As increasing amount of additional neutral particle density, ion and electron temperature decrease and plasma density builds up. Especially, the peak of plasma density moves from z = 10.04 m from z = 10.1 m. However, electron temperature does not decrease detachment front for high ion temperature. Therefore, it needs that ion temperature is decreased. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
