In March 2025, CERN received the first batch of jacks required to support and remotely align the HL-LHC magnets, TAXN absorbers, and crab cavity cryomodules. The jacks were designed by CERN and are currently under manufacturing by industry in Slovakia. This initial batch of six units successfully passed all tests, resulting in the greenlight for the series production of the remaining 134 units.
