Ezio Todesco (CERN)
WP3 contribution
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.
D1 and D2 and HO corrector review
In December 2018, a review of the design of the D2 correctors and HO correctors took place in CERN. The committee supported the selected designs that showed to reach the required performance.
Status of magnet test results
The last short model of the Nb3Sn quadrupole was limited below nominal current by one coil: to overcome this issue, the limiting coil shall be replaced magnet and the magnet shall be tested in summer.
Status of Magnet Production and Test Results
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.
Status of MQXF production and test results
After the successful tests of MQXFA03 and MQXFA04, that allowed last year to obtain the approval of the US contribution by the DOE, MQXFA05 has been tested in May 2021.
WP3 contribution - Issue 6
The magnet program has reached several milestones since the last annual meeting: in the following we summarize the main achievements of our collaborations.
