The ESS will become the world's most powerful neutron source when it goes into operation by the end of this decade.
INFN Milan contributed In-Kind by providing 36 superconducting cavities to be installed in the 9 Medium Beta cryomodules of the elliptical linac section.
LASA was responsible for the design of the cavities and conducted extensive testing with the prototypes, showing performance levels exceeding the ESS predefined goals.
Series production of the cavities took place at Zanon Research and Innovation (formerly E. Zanon). These cavities were qualified under cryogenic conditions at DESY before being delivered to CEA for string assembly and subsequent installation in the cryomodule.
The success of this contribution can be attributed to the effective synergy between INFN, the cavity supplier, DESY, CEA and ESS.
In particular, the last two cavities were delivered to CEA on November 17, completing the batch of the ninth cryomodule. The overall installation of cryomodules in the ESS accelerator is expected to be completed in the summer of 2024.
