Description
A compact RF linac design has been developed for an Accelerator Driven System (ADS). The linac is about 150 meters long and comprises a radio-frequency quadrupole (RFQ) and 20 superconducting RF cryomodules. Three types of half-wave cavities and two types of elliptical cavities have been designed and optimized for high performance at the frequencies of 162.5, 325 and 650 MHz. The lattice was designed and optimized for operation with a peak power of 25 MW for a 25 mA – 1 GeV proton beam. The cavities RF design as well as the linac lattice will be presented along with end-to-end beam dynamics simulations for beam currents ranging from 0 to 25 mA. We conclude with a discussion of the ADS reliability requirements, and the balance between compactness and redundancy of the RF linac.
