Description
Summary:The design and the fabrication of a new Lower Hybrid (LH) actively cooled antenna based on the passive active concept is a part of the CIMES project (Components for the Injection of Mater and Energy in Steady-state). The major objectives of Tore-Supra program is to achieve 1000 s pulses with this LH launcher, by coupling routinely > 3 MW of LH wave at 3.7 GHz to the plasma with a parallel index n(||) = 1.7 (c0.2). The launcher is on its way to achieve its validation tests - low power Radio Frequency (RF) measurements, vacuum and hydraulic leak tests - and will be installed and commissioned on plasma during the fall of 2009.
