摘　　要：Purpose To derive the temperature response of the basic unit of the electromagnetic calorimeter of the high energy cosmic-radiation detection(HERD)facility.Method Tested a method to measure HERD calorimeter cell(HCC)light yield using an ultraviolet Light-Emitting Diode with a wavelength of 300 nm,and established an experimental setup and tested the light yield of the HCC at different temperatures in a thermal chamber.Results and conclusions The result showed that the signal amplitudes variation of the HCC reached up to 10.2% with temperature ranging from 0 to 60℃,if we narrow the temperature range to 0-35℃,the variation was about 3.7% and it showed much better linearity.This result provides a good instruction on the thermal control of the HERD calorimeter(CALO)to improve its performance.
