设计了一种新型环折波导离子回旋共振频率天线，其输出功率为3 mW，工作频率范围为30~110 MHz。介绍了新型ICRF天线的关键部件设计和新型ICRF天线样机的特点。对法拉第屏蔽层和电流带进行了热力分析，并详细研究了考虑不同冷却水速时热负荷引起的应力。此外，还测试了该驱动系统对ICRF天线样机在真空条件下的可移动性。利用原发射机成功地对ICRF天线样机进行了工程调试。结果接近预期。
A new loop and fold wave-guide ion cyclotron resonance frequency (ICRF) antenna with a power output of 3 MW, which can operate at a frequency in the range of 30 MHz to 110 MHz, was designed. The design of key components of the new ICRF antenna and the characters of the new prototype ICRF antenna are presented. The thermo-mechanical analysis of both the Faraday shield and the current straps was conducted, and the stresses due to heat loads are studied in detail with different cooling-water velocities considered. In addition, the movability of prototype ICRF antenna under vacuum condition by the driving system was tested. An engineering commissioning was successfully performed on the prototype ICRF antenna using the original transmitter. The results are close to the expected.
