摘要

在荷兰Rijnhuizen的FOM等离子体物理研究所，一台高功率的静电自由电子微波激射器在不同频率下工作。7.2 a、1.77 MeV的电子束在206 GHz产生730 kW的输出功率，7.0 a、1.61 MeV的电子束在167 GHz产生360 kW的输出功率。后一频率下较低的输出功率是由于当前毫米波腔中相对较高的损耗。实验和仿真结果表明，根据电子束能量的不同，有限元方法可以在单频范围内工作。到目前为止，脉冲长度被限制在12 /spl mu/S左右。尽管如此，毫米波功率产生的许多方面已经进行了探索，例如对电子束电流和能量的依赖以及毫米波腔的设置。

The Dutch free-electron maser: 730 kW, 200 GHz

At the FOM Institute for Plasma Physics "Rijnhuizen", The Netherlands, an electrostatic high power free-electron maser is operated at various frequencies. An output power of 730 kW at 206 GHz is generated by a 7.2 A, 1.77 MeV electron beam, and 360 kW at 167 GHz is generated by a 7.0 A, 1.61 MeV electron beam. The lower output power at the latter frequency is due to relatively high losses in the present mm-wave cavity. It is shown experimentally and by simulations that, depending on the electron beam energy, the FEM can operate in single-frequency regime. So far, the pulse length was limited to some 12 /spl mu/S. Nevertheless, many aspects of generation of mm-wave power have been explored, such as the dependency on electron beam current and energy and settings of the mm-wave cavity.
