A new experiment seeks to examine equilibrium, stability, and confinement properties of toroidal electron plasmas. Electron plasmas with density about 3 x 10 exp 6cu cm are trapped for 100 micro seconds in a partially toroidal or C-shaped trap B200 G. Large amplitude oscillations are observed in the 100 kHz frequency range. The oscillation frequency is proportional to 1B and depends on the applied horizontal electric field, but not on the amount of charge in the trap. Some evidence points toward the ion resonance instability as the cause of these oscillations.
