Abstract.  Behavior and influence of two lithium capillary-pore system - based rail limiter models on the discharge parameters at heat fluxes of about 10MW/m² and discharge duration of 0.1 s have been experimentally investigated in a T-11M to substantiate the lithium capillary-pore system (CPS) application as a plasma facing material. Limiter thermal loads, plasma-limiter thermal balance, physics of lithium erosion and lithium accumulation in tokamak plasma have been studied. Reradiation effects in the lithium vapor at the plasma periphery has been detected and studied. The stability of lithium CPS under tokamak plasma conditions has been investigated and confirmed.
