In plasma flow generation experiment at the end-cell of GAMMA 10/PDX, ICRF heating in anchor-cell successfully extended the particle flux up to 3.3×1023 /m2 s. Superimposing the short pulse of ECH also attained the highest heat flux of ~25 MW/m2. We have succeeded in achieving and characterizing the detachment of the high temperature plasma equivalent to SOL plasma of tokamaks by using the divertor simulation experimental module (D-module) in the GAMMA 10/PDX end-cell in spite of using a linear device with short connection length of magnetic field line. Various gases (N2, Ne, Ar, Xe) are examined to evaluate the effect of radiation cooling against the plasma flow of MW/m2 level in a divertor simulation region and the following results are obtained: (i) Xe gas was most effective on electron cooling (down to ~2 eV) and reduction of heat and particle fluxes (1%, 3%, respectively). (ii) Ne gas was less effective. On the other hand, (iii) N2 gas showed more favorable effects than Ar. Numerical simulation using multi-fluid code was successfully performed in the end-cell and the effect of radiation cooling towards plasma detachment was investigated. These results will contribute to the progress in detached plasma operation and clarification of radiation cooling mechanism towards the development of the future divertor.}, title = {Recent Progress of Divertor Simulation Research Using the GAMMA 10/PDX Tandem Mirror}, year = {2016} }
