| Abstract: | A 16-channel J-type thermocouple instrument with digital calibration for the lower hybrid current drive (LHCD) system on HL-2M tokamak was developed to achieve 16 channel temperature measurements. The temperature measurement range is 0~250°C with the absolute error value less than 1°C. The temperature can be displayed on the liquid crystal display (LCD) and read on the computer remotely. The J-type thermocouple instrument has been successfully used in the debugging experiment of the LHCD heating system of HL-2M tokamak. The temperature of output cavity of the high power klystron has been measured under different output power conditions to ensure the safety of the klystron in operation. |
