Abstract :
In order to explore the characteristic of glow discharge cleaning (GDC) electrode of ITER and to support ITER GDC conceptual design, GDC tests are performed on SWIP GDC test bench. The setup of the GDC test bench is described. The tests focus on the breakdown, volt-ampere characteristics and heat load of helium and hydrogen glow discharge with recessed electrode, which is based on current ITER GDC conceptual design. Some results of such a recessed electrode and some unclear phenomena are shown.
