RFCD Power Requirements on ARIES-AT
and off-axis CD with LHW, for three ARIES-AT design points.
R = 5.2 m, A = 4, _ = 2.2, _ = 0.8, Ip ~ 13 MA, Bo ~ 6 T, Pnet = 1000 MW.
Full _N _(%)
5.6 8.4 15.8 0.925 3.0 21.7
6.0 9.2 15.9 0.943 3.9 21.2
6.8 10.6 17.8 0.915 4.2 65.1
than for ARIES-RS (~80 MW), due to higher bootstrap fraction and
better alignment.
Number of RFCD systems is reduced to two.
On-axis seed current is small, requiring only ~4 MW of ICRF power.
ECCD may be an attractive alternative.
