The last batch of the 54 high order corrector magnets was tested in LASA by the end of 2022, and all correctors have been delivered at CERN. In February 2023, a celebration was held to mark the end of the first production of HL-LHC magnets.

The HL-LHC magnets and cold powering systems are planned to be tested individually on dedicated test benches in the SM18 test facility at CERN or at the collaborators test facility (e.g. at Fermilab in the USA).

Uppsala University in Sweden has been a valuable collaborator since the foundation of CERN. In the 1950’s, Uppsala, having just constructed its own cyclotron, contributed to the development of the very first accelerator at CERN: the synchrocyclotron.

Since Issue3, three of the six series magnets were tested at cold [S1, S2, and S3], and another one [S4] is ready for testing on a test bench in SM18. On the production side, the construction of the cold mass assembly of the first spare magnet has started

The most significant advancement has been the test of the third US-AUP full size magnet (MQXFA03). It reached nominal gradient with limited training and is the first magnet ready to be included in the first cold mass to be installed in the IT-String test.
