摘　　要：电子回旋共振加热(ECRH)因其加热的定域性好、高效性和易操作等特点,成为许多托卡马克、仿星器等磁约束装置普遍采用的加热手段之一。微波波源高功率回旋振荡管是ECRH系统的核心设备,本文详细介绍了HL-2A装置ECRH系统的调试运行及实验,其中6套功率为0.5 MW、频率为68 GHz的ECRH系统可稳定运行输出2.5 MW功率并成功注入等离子体,2套功率为1 MW、频率为140 GHz的ECRH系统则可稳定运行输出1.8 MW功率。利用68 GHz ECRH系统,通过扫描沉积位置、功率、改变注入方式和与其它加料与加热的联合实验,在HL-2A装置上开展了ECRH及电流驱动等实验研究。Electron cyclotron resonance heating(ECRH)has become a commonly used heating methods in many magnetic confinement devices such as tokamaks and star simulators because of its good heating localization,high efficiency and ease of operation.High-power gyrotron microwave source is the core equipment of ECRH system.The commissioning,operation and experiment of ECRH system in HL-2A device were introduced in detail.Six sets of ECRH systems with power of 0.5 MW and frequency of 68 GHz can produce 2.5 MW stable output power and inject plasma successfully,and two sets of ECRH systems with power of 1MW and frequency of 140 GHz can produce 1.8 MW stable output power.Using the 68 GHz systems,some electron cyclotron resonance heating and current driving experiments were carried out on the HL-2A device by changing the injection parameters such as deposition region,injection mode,power level and so on.
