abstract = {An ICRH antenna system is under construction to be ready
for use in the operational phase 1.2 of W7-X. A two strap
antenna, with a surface adapted to the 3D shape of the Last
Closed Flux Surface (LCFS) of the standard magnetic
configuration (m/n = 5/5), will be installed in the
equatorial plane on the low field side of W7-X. The antenna
system is optimised for plasma heating and wall conditioning
in presence of the magnetic field in the frequency range
25–38 MHz. Each strap is short-circuited on one end, is
pre-matched using a tunable capacitor on the other end with
connection to the RF power source about halfway in the
poloidal direction. To allow optimal coupling to different
magnetic configurations in W7-X the antenna can be moved
radially over a distance of 350 mm. The cooling circuits in
the antenna head are designed to sustain cw W7-X plasma
operation in a retracted position and 2 MW ICRH pulses with
maximum 10 s duration every 300 s close to the LCFS.},
