Description
INFN LASA is advancing its in-kind contribution to the PIP-II project at Fermilab, with significant progress achieved in both cavity production and testing infrastructures.
The main activity is the fabrication of 38 five-cell β = 0.61 superconducting cavities for the LB650 section of the linac. Manufacturing is well advanced with mechanical production of the series cavities progressing while the two pre-series ones are being used to validate the complete industrial workflow, including surface processing and final preparation, that is mostly entrusted to industrial partners.
Crucial to ensure compliance with the stringent performance requirements of PIP-II, all cavities will undergo final qualification through a vertical cold tests facility at DESY AMTF (Germany) that is being finalized and commissioned. Lastly cavities will proceed with the delivery to CEA Saclay (France) as fully validated components ready for string assembly.
This contribution summarizes the status of these activities, presenting updates from the manufacturing of series cavities, results from pre-series qualification and recent upgrades to both LASA and DESY the testing infrastructures.
