A year and a half after the delivery of the prototype cryomodule (CM00) to ESS, the first production medium beta cryomodule (CM01) has now arrived at the ESS site. It left CEA on September 22, 2020 for a two-day trip to Lund, Sweden. The Irfu teams had previously validated the RF and cryogenic performances of this cryomodule. It will be tested again on the ESS test bench before being integrated in its final position in the accelerator tunnel. This is a first step.

On December 4, 2019, mechanical reception of the RFQ provided by Irfu took place in the tunnel of the European Spallation Source (ESS) project in Lund, Sweden. Following the delivery of the RFQ on August 27, 2019, the installation immediately followed with the Irfu team present and guaranteeing its success over the following months.

August 27, 2019, a key accelerator component from France was delivered to the European Spallation Source (ESS) in Lund, Sweden, as part of the French in-kind contributions to the next-generation research infrastructure. The Radio Frequency Quadrupole (RFQ) is the first accelerating structure in ESS’ linear accelerator and has been designed, developed and manufactured by the ESS French stakeholder CEA in its institute Irfu (Institute of Research into the Fundamental Laws of the Universe).

After more than 5 years of development, including 6 months of integration work of the 12,000 separate components to a complete cryomodule, the CEA-Irfu has just validated the technology of this complex system that reached the nominal ESS accelerating field in the 4 superconducting accelerating cavities.
