Fruitful Development Using a New Superconductor
An important milestone was achieved in June 2020 with the successful test at CERN of a demonstrator – Demo 2 – of the cold powering system for the HL-LHC magnets. Demo 2 incorporates a superconducting 60-m long power transmission line, the Superconducting Link, which will later be used to connect the HL-LHC magnets in the…

Latest News from Collimation
The HL-LHC-WP5 teams are extremely busy in LS2 because some of the key upgrades for HL-LHC will already be used in LHC Run3: In this challenging period, when most laboratories and companies were affected by the international crisis caused by the COVID-19, the companies involved in collimation production managed to continue working efficiently, though at…

RFD Assembly
Two prototypes of RF dipole cavities which provide horizontal crabbing for the HL-LHC were successfully built at CERN. The frequency tuning setup before the final two welds is shown in the figure below. The frequencies of both cavities were within 100 kHz (negligible) showing the surgical precision in the manufacturing techniques for such a complicated…
