Abstract
Dust particles appear on the edge of tokamak plasmas as a result of di sruptions and plasma interactions with divertor plates, limiters, or b lankets, as well as of pellet injections. It is shown that the presenc e of the dust impurities can lead to an effective decrease of the slow Alfven wave absorption in the region. These waves are used for heatin g, current drive, and control of the low-to-high(l-H) confinement tran sition. Radio-frequency forces can also be strongly changed in the pre sence of dust particles.
