Abstract
  • For the upper launchers of the 170 GHz electron cyclotron resonance heating (ECRH) and current drive system of ITER, \"remote steering\" based on the imaging properties of corrugated square waveguides is the reference option. In the last years, a variety of numerical simulations and experimental investigations of a remote steering launcher (RSL) mock-up were performed and demonstrated the feasibility of this con-cept. In this paper, low- and high-power experiments of a remote steering antenna mock-up are presented and compared. The tests included re-cording of radiation patterns, ohmic loss measurements, and explor-ation of the limits for breakdown. All measurements were performed with a straight launcher mock-up as well as with a dog-leg version with two integrated mitre bends. It is shown that the usable steering range of the antenna is ±12°, and that optimized mitre bends can be integrated without prohibitive extra loss. Consequences for the design of the upper launcher on ITER are discussed. (literal)
