Summary:A systematic experimental study of the power, length, and gas pressure dependence of plasma density and temperature profiles in thermally collapsed magnetized helium plasmas has been performed on the Princeton divertor simulator apparatus. The recombination edge and recombination radiation from highly excited levels (to n = 12) have been identified. The importance of radiation and neutral particles to heat transport has been demonstrated. A region of stable plasma detachment has been found and is suggested as being suitable for divertor operational space.
