Abstract
During the first year of operation, the TCV tokamak has produced a large variety of plasma shapes and magnetic configurations, with 1.0torp-1 corresponding to a stability margin f=1.15, have been stabilized. Ohmic H-modes, with energy confinement times reaching 80 ms, normalized beta ( beta toraB/Ip) of 1.9 and tau E/ITER89-P of 2.4 have been obtained in single-null X-point deuterium discharges with the ion grad B drift towards the X-point. Limiter H-modes with maximum line averaged electron densities of 1.7*1020m-3 have been observed in D-shaped plasmas with 360 kAp<or=600 kA.Keywords
