Initial design studies of a heavy-ion beam probe that would be capable of accessing the full plasma cross section of Texas Experimental Tokamak upgrade showed that it would require a 2-MeV Tl+ beam. Such a beam probe would have an estimate sensitivity for measuring broadband potential fluctuations of 2 V rms, an accuracy for measuring potential profiles of ±40 V, and a resolution for measuring normalized broadband density fluctuations of 0.1%.
