摘要
电子回旋加热(ECH)是一种最常用的对仿星器等离子体进行加热的方法，既可以为启动提供电离，又可以在放电过程中提供净电流加热。本文介绍了哥斯达黎加仿星器(SCR-1)的ECH加热系统的设计，SCR-1是哥斯达黎加研究所Tecnológico de Costa Rica (ITCR)正在建造的一个小型模块化仿星器。SCR-1是一种小型(主半径0.238 m，平均等离子体半径0.042 m)低预算器件，使用2周期磁场，具有平坦的旋转变换曲线(ir =0.3)，谐振强度为8.78×10−2 T，期望达到15 eV温度，电子线密度为3.74×1015 m−3。
Design of an ech system for a small modular stellarator
Electron cyclotron heating (ECH) is one of the most common methods used for heating stellarator plasmas, providing both ionization for startup and net-current free heating during the discharge. This paper presents the design of the ECH heating system for the Stellarator of Costa Rica (SCR-1), a small modular stellarator under construction at the Instituto Tecnológico de Costa Rica (ITCR). The SCR-1 is a small (Major radius 0.238 m, mean plasma radius 0.042 m) low budget device, using a 2 period magnetic field with flat rotational transform profile (ı=0.3), a resonant strength of 8.78×10−2 T and expected to achieve a 15 eV temperature with an electron line density of 3.74×1015 m−3.
