LHCb's new VELO preparing to spring into action

The replacement of the previous VErtex LOcator (VELO) detector with a new high-speed hybrid pixel detector was one of the key milestones for the LHCb collaboration in 2022 (see also previous EP newsletter article). The upgrade was part of an R&D…

Ending the 2023 LHC run with heavy-ion collisions

The LHC schedule for 2023 has been revised following the emergence of a leak in mid-July. The decision was to stop the regular proton running this year and focus on the heavy ion physics that was already scheduled for the year-end. This was…
