Abstract

The Alcator C-Mod tokamak experiment relies on ICRF heating as the sole source of auxilliary power. Two different antenna designs have been produced and fabricated for the ICRF heating experiments. The first antenna has a single current strap, a two-layer Faraday shield, and is movable radially. One of these antennas was built, conditioned to high RF voltage on a test stand, and installed on C-Mod for the first experimental run. The engineering goals of the first experiments include measuring the plasma loading and testing the power handling capability of the antenna. Details of the conditioning and tuning procedures will be presented. The second antenna has two phasable current straps and a single layer Faraday shield. The predicted high disruption forces require that it be attached securely to the vacuum vessel wall at a fixed radial position. Two of these antennas have been constructed, one having a titanium carbide coated Faraday shield and the other a boron carbide coated shield. They are designed to couple up to 4 MW of source power from two FMIT transmitters. Details of the fabrication and test stand conditioning of these antennas will be presented.

alcatator C-Mod托卡马克中ICRF加热天线

alcater C-Mod托卡马克实验依靠ICRF加热作为辅助电源的唯一来源。为了进行ICRF加热实验，我们制作了两种不同的天线设计。第一个天线有一个单一的电流带，一个两层法拉第屏蔽，并可径向移动。其中一个天线已经建成，在试验台上适应高射频电压，并安装在C-Mod上进行第一次实验运行。第一次实验的工程目标包括测量等离子体载荷和测试天线的功率处理能力。详细的条件和调整程序将提出。第二个天线有两个可相位电流带和一个单层法拉第屏蔽。预测的高破坏力要求它在固定的径向位置安全地附着在真空容器壁上。其中两个天线已经建成，一个有碳化钛涂层的法拉第屏蔽，另一个有碳化硼涂层的屏蔽。它们被设计为从两个FMIT发射机耦合高达4兆瓦的源功率。详细介绍了这些天线的制造和试验台条件。
