Measurements of the abundance of multiply charged ionization products from a heavy ion beam probing beam have been used as a spatially resolved plasma diagnostic on Elmo Bumpy Torus. Radial profile measurements demonstrate that two classes of electrons are present: those that communicate toroidally to form the core plasma and those that are mirror trapped and depend on local heating (particularly ω = 2Ω[sub ce]) for their existence. Both types show a systematic dependence on resonant heating locations.
