Abstract

300 GHz CW gyrotron FU CW I has been developed and installed in University of Fukui. Performance test has been carried out and the maximum power of 1.75 kW / CW has been attained. The radiation pattern of the output beam has been measured in detail with an infrared camera. It has been confirmed that the output beam propagates as a Gaussian beam with high purity. However, the output power is radiated into multiple directions within a range of the magnetic field strength at the cavity, which indicates simultaneous oscillation of competing cavity modes.
300 GHz连续波回旋管FU连续波辐射方向图分析
300 GHz连续波回旋管FU CW I已研制完成并安装在福井大学。进行了性能试验,达到了1.75 kW / CW的最大功率。用红外摄像机对输出光束的辐射方向图进行了详细测量。结果表明,输出光束以高纯度的高斯光束传播。然而,输出功率在腔处磁场强度范围内向多个方向辐射,这表明竞争腔模式同时振荡。
