Abstract.  In this work the divertor plate behavior has been simulated in the quasi-stationary condition. In the previous experiments on T-11M the CPS quasi-stationary heat state has not been achieved for pulse length ($ \leq$0.1 s). The T-11M tokamak up-grade allowed its performance to be increased as follows: plasma current up to 100 kA, pulse length 0.2-0.3 s. The new lithium limiter (Fig. 1) unlike the previous versions has a thermal regulation system which permits a lithium surface initial temperature to be given from -196 to 600oC. This provides for an increase in test parameter range: sorption and desorption of plasma-forming gas, lithium emission into discharge, lithium erosion, limiter deposited power and so on. The first results of experiments were presented.
