ICRF heating scenarios in Alcator C-MOD
- MIT Plasma Fusion Center, Cambridge, Massachusetts 02139 (United States)
Alcator C-MOD tokamak ([ital R]=0.67 m, [alpha]=0/21 m, [kappa cur]1.8, [ital B][le]9 T, [ital I][le]3 MA) will start operating in April 1993. Initially 2 MW of rf power at 80 MHz will be available, which will be upgraded to 4 MW by early 1994. Additional 2--4 MW of 40--80 MHz tunable power may be installed in 1996 in collaboration with PPPL. With the 80 MHz transmitters, He[sup 3] minority heating at [ital B]=7.9 T and H minority heating at 5.3 T are the main heating scenarios, with possibilites of He[sup 3] and H second harmonic minority heating (at 3.9 T and 2.6 T, respectively) and direct electron heating by ELD/TTMP. The tunable transmitter will enable fundamental He[sup 3] and H minority heating at lower fields, and Alfven wave heating below the ion cyclotron frequency at fields above 4 T in H plasmas. Advanced tokamak scenarios with high bootstrap current fraction and high normalized beta can also be studied in combination with pellet fueling and 4.6 GHz LHCD under TPX-like conditions ([ital B][similar to]4 T, [ital [bar n]][sub [ital e]][approx lt]1[times]10[sup 20] m[sup [minus]3]) for pulse lengths exceeding the L/R time.
