Abstract：A temperature control system for ring-down cavity is developed.The temperature control box with silicone heating plate on the inner wall is designed firstly, which the ring-down cavity is placed in. The internal temperature distribution is simulated. The finite element analysis and parametric scanning are carried out to get the optimized distribution and power of the heating plate to ensure the temperature uniformity along the light-transmitting part of the cavity. According to the simulation results, the actual box and heating plate are fabricated. Then, the hardware circuit system including temperature sampling module, control module and drive circuit module are designed with PID control algorithm as the core, and the corresponding control algorithm is developed to precisely control the cavity temperature change. After the precision temperature control system is completed, the standard deviation of the temperature variation along the light-transmitting part of the ring-down cavity is less than 0.01 ℃ in 8 hours.
