Experimental dependencies of τE on n, q and R in the T-13 tokamak

Consideration is being given to results of experimental investigation at the T-13 tokamak of dependence of confinement time in electron τE component on plasma density safety factor, discharge current, large radius R. It is shown in the region of τE linear dependence on density that conditions exist under which τE/n value (where n - plasma density) doesn't depend on large radius as well as condition under which τE/n depends on large radius τE/n ∼ Rγ where γ ≥ 2. This condition corresponds with τE/n maximal value for the given experiments
