Description

The stable cooling system is an important system for a stable operation of the RF cavity. The new RF cavity system was installed in the Siam Photon Source (SPS) in 2016. The new cavity is kept running with
42-degree Celsius water cooling system. There were several problems with the cooling system during one-year operation. The main problem is the heat accumulate in the system. The activities to decrease this
accumulated heat in the cooling unit is in progress. The study to decrease the cooling temperature is also started. Decreasing water temperature will prolong operation of water cooling unit and help a bit of
reducing electricity consumption. The activities are concerned the changing position of tuner to get the operation frequency with the temperature changing. The cavity is a capacitive loaded type and is tuned by
changing the capacitor gap. This deforms shape of the cavity, which affects the higher order mode (HOM) frequencies. The study of these HOMs with the temperature and the effect to the stored beam will be
presented.
