摘要

电子回旋加速器发射诊断（ECE）系统是在 ENN 球形环（EXL-50）上开发的。该系统旨在探测频率范围为 4 至 40 千兆赫的高能电子辐射。该系统由五个不同频段的子系统组成，即 C 波段（4-8 千兆赫）、X 波段（8-12 千兆赫）、Ku 波段（12-18 千兆赫）、K 波段（18-26.5 千兆赫）和 Kα 波段（26.4-40 千兆赫），并采用外差探测技术。K 波段和 Kα 波段子系统水平安装在 EXL-50 的赤道平面上，而 C 波段、X 波段和 Ku 波段子系统则垂直安装在 EXL-50 的真空容器下。已开发出准光学系统，将等离子体的微波引向水平探测子系统的天线。用于垂直探测的天线直接连接到环体下方 R=700mm 处的端口，即环体的磁轴。将详细介绍系统集成、台架测试和初步实验结果。

Design of the electron cyclotron emission diagnostic on EXL-50 spherical torus

The electron cyclotron emission diagnostic (ECE) system has been developed on ENN Spherical Torus (EXL-50). The ECE system aims to detect radiation from energetic electrons in the frequency range from 4 to 40 GHz. The system is composed of five subsystems with different frequency bands, i.e., C-band (4-8 GHz), X-band (8-12 GHz), Ku-band (12-18 GHz), K-band (18- 26.5 GHz) and Kα-band (26.4-40 GHz), and it using heterodyne detection. K-band and Kα-band subsystems are located horizontally in the EXL-50 equatorial plane while C-band, X-band and Ku-band subsystems are vertically located under EXL-50 vacuum vessel. The quasi-optical system has been developed to direct the microwaves from plasma to the antennas for horizontal detection subsystems. The antennas for vertical detection are attached directly to the port beneath the torus at R=700mm, i.e., the magnetic axis of the torus. The system integration, bench test and the initial experimental results will be given in detail.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
