Abstract
We have performed two dimensional fluid B2 simulations on detached recombining plasmas to compare with experimental observations in a linear divertor plasma simulator. In detached helium plasmas associated with volumetric electron-ion recombination (collisional radiative recombination), an electron-ion energy exchange process followed by ion-neutral charge exchange is found to be a key to reduce the electron temperature along the magnetic field to be less than leV. The structural change of detached plasmas associated with molecular activated recombination has been also discussed in detail.
