AbstractExperiments have been performed with the free-electron maser (FEM) at Rijnhuizen, a high-power mm-wave source. A unique feature of the FEM is the possibility to tune the frequency over the entire range from 130 to 260 GHz at an output power exceeding 1 MW. In the so-called inverse set-up, where the electron gun is mounted inside the high-voltage terminal, a peak power of 730 kW was measured at 200 GHz and of 350 kW at 167 GHz [1], [2]. Furthermore, we made the design work to extend the pulse-length to 1 s. Detailed thermal behavior of the critical components is studied. Both the cavity mirrors and the depressed-collector electrodes seem to have adequate cooling.

自由電子メーザー(FEM)を用いた実験を、高パワーのミリ波源であるラインハイゼンにおいて実施した。FEMの特筆すべき特徴は、130 GHzから260 GHzまでの全範囲にわたって周波数を同調でき、その際の出力電力は1 MWを超えることである。いわゆる逆セットアップ構成(電子銃が高電圧端子の内部に取り付けられた構成)では、200 GHzにおいて730 kW、167 GHzにおいて350 kWのピーク電力が測定された。さらに、パルス長を1秒に延長するための設計作業を行った。主要構成要素の熱的挙動について詳細な検討がなされた。空洞ミラーとコレクタ電極の両方について、冷却は十分であると思われる。
