NBI heated plasmas are best for this as the plasma is not affected by a density cut-off limit, as can occur for injections into ECRH plasmas. The standard magnetic configuration with one or both NBI heaters working will be employed. In order to avoid frequent entries into the TJ-II experimental hall (to change the TESPEL revolver position) this experiment should be run in conjunction with cryogenic pellet or LBO experiments. Thus it may take several days to complete the studies.

Given the need to minimize such entries the number of TESPELs to be injected will be limited. Thus experiment can be run in conjunction with pellet or LBO experiments.
