摘 要:
新研制的微波功率测量系统主要由温度传感器、功率标定电源、电子学处理单元、数据采集和数据处理单元等几部分组成，通过测量EC系统MOU部件冷却水回路进水口和出水口的温度变化，得到MOU吸收的杂模功率。根据回旋管输出功率中的杂模含量比，计算得到回旋管的输出功率。在回旋管调试和ECRH实验期间，测量了4路回旋管的输出功率。从测量结果可知，HL-2A装置ECRH系统可提供大于1．6MW的总输出功率。[著者文摘]

Abstract:
Spurious mode power absorbed by MOU of the gyrotron is measured by detecting increment of the temperature difference between inlet and outlet of cooling water flowing through MOU with a calorimetric system, which consists of temperature sensors, timing power supply, electronic processing unit and data gathering and handling unit etc. The output power of gyrotron, therefore, is calorimetrically monitored based on the measured spurious mode power and its contents. In this way, four gyrotrons are measured during commissioning and ECRH experiments, and the results show that over 1.6 MW of the total output power provided by ECRH system on the HL-2A tokamak is obtained.[著者文摘]
