Abstract
The formation of detached Ar plasma at the undirectional or directional contact of Ar or H2 gas has been carried out experimentally from the viewpoint of the cooling of the Ar plasma concerned with a fundamental research on the gas divertor by using the magnetized sheet plasma. The detached plasma forms easily by the directional contact of H2 cooled gas. On the other hand, no detached plasma forms by the contact of Ar gas.
