抄録

The axial profile of Balmer-alpha emission near a tungsten target has been measured in the compact plasma wall interaction (PWI) simulator Advanced PWI Simulation Experimental Device and Analysis System (APSEDAS). Axial H α emission decreases toward the target at two levels, a steep gradient within 10mm of the target and a shallow gradient more than 10mm away. The structure of the H α profile within 40mm of the target is the same even though the electron density changes by one order of magnitude and the neutral pressure changes by a factor of three. On the other hand, the H α profile more than 40mm from the target gradually increases with increasing hydrogen filling pressure, although it does not change with the density in the case of constant filling pressure.
