AbstractFor the future stellarator W7-X of IPP at Greifswald, a powerful electron cyclotron resonance heating facility is being built which will include 10 gyrotrons at 140 GHz with a CW power of 1 MW each plus two optional gyrotrons at 70 GHz. The millimetre wave power will be transmitted fully optically via two multiple-beam wave guides (MBWG) with a length of about 50 m. This paper presents calculations and low-power measurements of the transmission characteristics of a prototype MBWG, which promises a high transmission efficiency for the ECRH system under construction. Furthermore, tests of prototype water-cooled mirrors are discussed.

将来のIPPグライフスヴァルトのW7-Xステラレーターのために、強力な電子サイクロトロン共鳴加熱装置が建設中であり、140 GHzで各1 MWの連続波出力を持つ10基のジャイロトロンに加え、70 GHzで動作する2基のオプション用ジャイロトロンが含まれる予定である。ミリ波電力は、約50 mの長さを持つ2本のマルチビーム導波管(MBWG)を介して完全に光学的に伝送される。本論文では、建設中のECRHシステムに高い伝送効率を約束するプロトタイプMBWGの伝送特性に関する計算と低出力測定結果を提示する。さらに、プロトタイプの水冷ミラーの試験についても議論する。
