Abstract :
New storage ring cavity temperature system was successfully operated for the Pohang Light Source (PLS) and increased the stable maximum beam current up to 200 mA. The storage ring cavity for PLS has the plunger-type tuner which is controlled by the phase feedback loop to always tune the resonant frequency. Optimum temperature windows for the PLS cavities were obtained by intensive but tiresome measurements. The measured results is compared to the calculation based on the relations expressed as a function of the tuner position
