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. [...]

CALCULATING THE CHANNELLING EFFICIENCY OF BENT SILICON CRYSTALS USING TWO PARTICLE SIMULATION PROGRAMS: SIXTRACK AND XSUITE / Dewhurst, Kay (CERN) ; Pascal, Hermes (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN) ; Van der Veken, Frederik (CERN)
A novel double-crystal experiment is being considered for installation in CERN’s Large Hadron Collider (LHC) to measure precession properties of short-lived baryons such as the Λ+𝑐. The experiment utilises a first bent silicon crystal of 50 μrad to deflect halo particles away from the circulat- ing proton beam. [...]

SPS Fast Spill Monitor Characterisation and Evaluation Throughout 2023 / Benitez Berrocal, Sara (CERN) ; Belohrad, David (CERN) ; Burger, Stephane (CERN) ; Goldblatt, Aurelie Noelle (CERN) ; Martin Nieto, Miguel (CERN) ; Mazzoni, Stefano (CERN) ; Roncarolo, Federico (CERN)
Monitoring the intensity of protons extracted from the CERN Super Proton Synchrotron )SPS) ring towards the North Area (NA) facility at a high rate is of utmost importance, with increasing challenges, for the the current facility operation, the ongoing NA consolidation, and the future Physics Beyond Colliders (PBC) projects. Various instruments are being developed to measure beam current fluctuations across a broad range of frequencies, from a few hundred Hz to several hundred MHz. [...]
