Results of the Cryogenic Testing of the SNS Prototype Cryomodule

PDF Version Also Available for Download.

Description

Jefferson Lab has developed a prototype of the medium beta SNS cryomodule. Tests were recently performed on the module, which includes three 805 MHz cavities of beta=0.61, with coaxial power couplers and frequency tuners (mechanical and piezoelectric). The cavities exceeded accelerating gradients of 16 MV/m (design value 10.5 MV/m) with Q{sub 0}'s of about 10{sup 10} at the design field. One of the power couplers has been tested up to peak powers of over 700 kW. Results of the tests are reported in this paper.
