Moving Divertor Plates in a Tokamak

“…4. Similar processes steps were described previously for the other moving divertor ideas [4][5][6][7][8][9].…”

“…Research on the main difficulties such as motion in vacuum and rapid plate cleaning and inspection can be done without a tokamak [e.g. 5,8]. It is not yet clear whether a moving plate system would be more or less feasible than other similar ideas for movable divertors, e.g.…”

“…These processing and inspection steps could all be developed on test stands without a tokamak [e.g. as in 5,8].…”

“…The pebble divertor [6,7] would perform similar functions, but with a gravity-driven stream of small pebbles falling through the divertor. The liquid wall divertor would perform the same functions with a moving liquid stream or gravity-driven droplets [8,9]. However, so far the only moving surfaces used in a tokamak were a rotating limiter tested on PLT [10] and a gallium droplet limiter tested on T-3M [8].…”
