| Abstract |
A cryomodule integrating two superconducting radiofrequency (SRF) double Spoke cavities and their RF power couplers is now being assembled at IPNO. It is the prototype version of the 13 future cryomodules composing a 56 meters long double Spoke section which will be operated for the first time in a linear accelerator (linac) for the European Spallation Source (ESS). ESS will be the most powerful neutron source feeding multidisplinary researches. This cryomodule provides the cryogenic environment for operating the two '=0.5 cavities at full power in a saturated superfluid helium bath at a temperature of 2 K. Thermally and magnetically shielded, they will each be fed by a 352 MHz electromagnetic wave, with a peak power of 400 kW, to generate an accelerating pulsed field of 9MV/m. For this operation, the prototype cryomodules includes all the interfaces with RF, cryogenics, vacuum, beam pipe and diagnostics. It will be tested by 2016 at IPNO by use of a test valve box which is also a prototype of the future Spoke cryogenic distribution system, another contribution to ESS. Both prototypes will then be tested at full power at Uppsala university FREIA facilities.
