Half of the US-AUP magnet production at CERN
At the end of October we received two more magnets from Fermilab (CA03 and CA05). With these deliveries, half of the units from the US are at CERN! They join the other three magnets already received: CA01 and CA02 for the IT String, and CA04.

New beam dump design for High-Luminosity stored beam energies
In the LHC beam dumps, the energy stored in the proton beams must be safely absorbed by the core materials. Due to their exceptional thermal shock and radiation resistance, carbon-based materials have been successfully used for this purpose since LHC Run 1. In the High-Luminosity (HL) era, the maximum stored energy in each LHC beam…

Collider-experiment interface: how engineers are preparing for manoeuvres in this highly restricted region of the HL-LHC
Engineers have started to use a life-sized mockup, named GALLUS V2, of the highly restricted region between the collision points and the tunnel at ATLAS and CMS, to test alignment and handling procedures.

The cold sets in: cryogenic installations | CERN News
The delivery of two huge compressors kicks off the installation of the new helium refrigerators for the High-Luminosity LHC. As manufacturing of the components for the HL-LHC reaches its final stages, installation activities are gaining pace. Six impressive compression units have just been delivered by Linde Kryotechnik and installed in the new HL-LHC surface buildings…
