Impedance Studies on the LHC Interconnect Modules / Dissanayake, Maleesh (Université Paris-Saclay (FR))
During the third run of the Large Hadron Collider in 2023, characterized by the highest intensity bunch population to date, a beam dump incident with operational delays occurred due to increased losses linked to pressure spikes within a warm vacuum sector. Inspections revealed localized annealing and degradation of tension springs in interconnecting vacuum modules. [...]

Chapter 22: Integration, (De-) Installation and Alignment / Fessia, P (CERN) ; Durand, H Mainaud (CERN)
Optimized space allocation for each equipment is instrumental to ensure that the various systems perform according to specification and to minimize installation and maintenance time. The general optimization effort goes under the name of “integration”, and it is strictly linked to the de-installation of the previous machine, to the management of the interfaces with existing infrastructures and to the installation of the new HL-LHC equipment. [...]
