Heating Techniques
The 73 MW start-up set of heating and current drive systems consists of
33 MW of neutral beam (1 MeV), 20 MW of ion cyclotron (~50 mMHz), and
20 MW of electron cyclotron (170 GHz) heating. Possible options to upgrade
the power to 130 MW include doubling the power of both rf systems to 40
MW each, increasing the neutral beam power to 50 MW, and adding 40 MW
of lower hybrid (~5 GHz) power.
