The first of 13 “spoke” cryomodules of the CNRS contribution to the Europena Spallation Source (ESS) has arrived in Uppsala, Sweden. As part of the CNRS contribution to the construction of the ESS, IJCLab took charge of the design and construction of the entire so-called “spoke” section of the proton accelerator, i.e. around 56 meters of structures. acceleration which brings the particle energy from 90 MeV to 220 MeV. The technology retained is that of superconducting cavities called "spoke", grouped in pairs within cryomodules, and for which this will be the first time they have been implemented in an accelerator. After several years of design and prototyping, the IJCLab teams prepared and assembled on the laboratory's SupraTech platform the first of 13 serial cryomodules. Departing by IJCLab truck on Tuesday, October 13, the cryomodule has arrived safely at Uppsala University in Sweden, the test and power qualification site for spoke cryomodules. After validation of its performance, the cryomodule will leave for Lund, ESS's host site, to be installed in the accelerator tunnel. Congratulations to all the IJCLab teams for this important milestone reached!
