Design of an Electron Gun for a 280 GHz Induced-Resonance-Electron Cyclotron (IREC) Maser Experiment

Abstract

The induced resonance electron cyclotron (IREC) maser is a promising source of high power radiation in the 100 GHz to 500 GHz frequency range that may impact the requirements of advanced systems for applications such as high- resolution radar. The IREC maser can provide mm and sub-mm radiation in the first electron cyclotron harmonic using currently available magnet technology. The IREC maser eliminates the problem of the low frequency oscillation from the CARM by providing a quasi-optical (QO) cavity structure that will not support the low frequency modes. In addition, in the IREC maser, as in the QO gyrotron, the radiation is naturally decoupled from the electron beam. Since the IREC maser is an oscillator, it requires no driver source, a strong advantage at frequencies over 100 GHz.
