Аннотация:
During the first year of operation, the TCV tokamak has produced a large variety of plasma shapes and magnetic configurations, with 1.0<or=B<sub>tor</sub><or=1.46 T, I<sub>p</sub><or=800 kA, kappa <or=2.05, -0.7<or= delta <or=0.7. A new shape control algorithm, based on finite element reconstruction of the plasma current in real time, has been implemented. Vertical growth rates of 800 sec<sup>-1</sup> corresponding to a stability margin f=1.15, have been stabilized. Ohmic H-modes, with energy confinement times reaching 80 ms, normalized beta ( beta <sub>tor</sub>aB/I<sub>p</sub>) of 1.9 and tau <sub>E</sub>/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*10<sup>20</sup>m<sup>-3</sup> have been observed in D-shaped plasmas with 360 kA<or=I<sub>p</sub><or=600 kA.
