Gaseous divertor simulation in an arc-jet device
The first experimental simulation of the gaseous tokamak divertor is presented. Significant results are: (1) neutral gas at a pressure of a few mTorr is sufficient to absorb the entire localized flux of plasma thermal energy and reidstribute it over a wide area; (2) elastic ion-neutral collisions constitute the main energy absorbing process (at T/sub e,i/ less than or equal to 5 eV), and (3) a large pressure difference between divertor and main plasma chamber is maintained by plasma pumping in the connecting channel.
