| Title | Development of a prototype superconducting radio-frequency cavity for conduction-cooled accelerators | ||||
| Abstract | The higher efficiency of superconducting radio-frequency (SRF) cavities compared to normalconducting ones enables the development of high-energy continuous-wave linear accelerators (linacs). Recent progress in the development of high-quality Nb3Sn film coatings along with the availability of cryocoolers with high cooling capacity at 4 K makes it feasible to operate SRF cavities cooled by thermal conduction at relevant accelerating gradients for use in accelerators. A possible use of conduction-cooled SRF linacs is for environmental applications, requiring electron beams with energy of 1 10 MeV and 1 MW of power. We have designed a 915 MHz SRF linac for such an application and developed a prototype single-cell cavity to prove the proposed design by operating it with cryocoolers at the accelerating gradient required for 1 MeV energy gain. The cavity has a ? 3 ?m thick Nb3Sn film on the inner surface, deposited on a ? 4 mm thick bulk Nb substrate and a bulk ? 7 mm thick Cu outer | ||||
