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.
