A divertor simulation experimental module (D-module) with a V-shaped divertor target is installed in the west end-sell in GAMMA 10 large tandem mirror device, and a hydrogen plasma irradiation experiment to the target have been started to investigate radiation cooling mechanism on the target. A gas injection system is installed in the D-module and Langmuir probe and calorie meter array are mounted on the target plate. During the plasma irradiation, the highest electron density of 2.4 10 m and a significant reduction of the electron temperature from a few tens of eV to 2 eV are achieved on the target plate by hydrogen and noble gas injection into the D-module.
