Thermal studies of high-pressure RF cavities were performed to analyze the natural convection in the gas inside the cavity. The natural convection is driven by the deposition of energy in a circular cross-section along the axis of the cavity. Non-dimensional analysis was implemented and thermal solutions were obtained over a wide range of geometrical and thermal variables. In this talk, the thermal results at high values of Rayleigh number including heat transfer coefficient, flow temperature, and flow velocity will be discussed. Also, thermal and structural design considerations of RF windows for high-pressure RF cavities will be proposed.
