A complex of tungsten and lithium limiters is developed. It is expected that application of W as a plasma facing material will allow excluding carbon influx into the vacuum chamber. An additional Li limiter, arranged in the shadow of the W one, will be used as a Li source. The parameters and design of limiters are presented. The plasma facing surface of the Li limiter is constructed to make use of a capillary-porous system (CPS). The porous matrix of the CPS provides stability of liquid Li surface under magnetohydrodinamic force effects, and facilitates its constant renewal due to capillary forces. It is shown that the upgrade of limiters in tokamak Т-10 will allow the provision of electron cyclotron resonance (ECR) plasma heating with power up to 3 MW at reasonable Li flux. The first results on Li-W experiments with ECR heating are presented and discussed. Li limiter design and limiter arrangement configuration for a steady state operating tokamak with a closed cycle of lithium circulation are considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
