✦ Synopsis

The thermal breakdown is unacceptable for high power use of superconducting rf cavities. Limitations of rf field both in He/and Hell baths were estimated and discussed on C-band TEOI 1 mode niobium cavities. Calculations were performed by a simulation program under the different assumptions of Kapitza resistance, thermal conductivity and wall thickness, taking lateral heat flow and curvature of the wall into account.
