 note = {"A second hanmonic electron ccyclotron heating ( ECH ) discherge was sustained for ~ 20 s in the Advanced Toraidal Facility ( AT F ) at relatively weak magnetic field of B = 0.63 T. The high electron temperature ( T_eo ~ 700 eV ), helium plasmas were produced with ECH power of P = 100-200 kW from a 35 GHz gyrotron. The line-averaged electron density, bar{n}_e', and stored plasma energy, W_dia', were 2.3 x l0^18 m^-3 and 300-500 J, respectively. The stored energy follows closely the gyro-reduced Bohm confinement scaling law. The maximum discharge duration was limited by ECH pulse duration but not by plasma collapse. Diagnostic signals showed attainment of a quasi-stationary plasma and no impurity build-up was indicated by soft x-ray and VUV spectroscopic signals."},
