Observation of the Periodical Movement of Ionized Front in a Closed-Divertor Simulator

The dynamics of plasma and the reversal flow of neutral particle are investigated experimentally in a closed-divertor simulator. It is observed that the ionized front periodically moves in and out of the closed divertor region, as the neutral gas is injected sufficient amount for achieving plasma de...

Zusammenfassung:	The dynamics of plasma and the reversal flow of neutral particle are investigated experimentally in a closed-divertor simulator. It is observed that the ionized front periodically moves in and out of the closed divertor region, as the neutral gas is injected sufficient amount for achieving plasma detachment in the divertor region. Such movement can be related to the reversal flow of the neutral particles injected.
