Abstract

The high-luminosity large hadron collider (HL-LHC) is a novel machine configuration which will rely on a number of key innovative technologies to enhance the performance of the present LHC machine as of 2025. The upgrade will also involve increased radiation levels that need to be predicted by combining scaled measurements and calculations in order to define the qualification requirements for electronic systems. In this paper, we describe such levels, first of all, by introducing the monitoring and calculation approaches used for the present LHC machine, and second, by applying scaling factors and dedicated simulations for the future HL-LHC accelerators. We present the levels according to the different areas relevant for the operation of electronics-based equipment, and discuss the associated radiation hardness assurance implications.

E. H. Maclean, F. S. Carlier, J. Dilly, M. Le Garrec, M. Giovannozzi, R. Tomas

Summary: Nonlinear magnetic errors in low-beta insertions can significantly impact the beam dynamics of colliders. Correction of such errors is crucial for improving operational benefits. This paper assesses the feasibility of beam-based observables for correcting dodecapole order errors in the experimental insertions of the HL-LHC, based on experience from the LHC's second operational run.

Summary: The beam tails in the CERN high-luminosity large hadron collider (HL-LHC) upgrade pose significant challenges due to orbit jitters and the large amount of stored energy. The use of hollow electron lenses (HELs) is considered the most promising approach to control and deplete the overpopulated tails.

Long term aging test of the new PMTs for the HL-LHC ATLAS hadron calorimeter upgrade

F. Scuri

Summary: The central hadron calorimeter of the ATLAS experiment uses around 10,000 photomultipliers (PMTs) for readout. Previous studies have shown a degradation in PMT response as the integrated anode charge increases. A model was created to simulate the time evolution of the PMT response and projected a loss of over 25% for about 8% of the PMTs that will integrate an anode charge of 600 C, expected at the end of the High-Luminosity LHC program. These PMTs will be replaced with a newer version to maintain optimal global detector performance. A local test setup in the Pisa laboratory is being used to study the long term response of the new PMT model considered for replacement in the hadron calorimeter readout of the most active cells. Preliminary results from data collected in the Pisa laboratory are presented.

P. Kumar, B. Gomber, CMS Collaboration

Summary: The high-luminosity large-hadron collider (HLLHC) is expected to achieve high-precision measurements and evaluations of the standard model (SM) and explore new physics. The success of the HL-LHC program relies on efficient data collection and precise event reconstruction in the challenging environment of 200 proton-proton interactions. To meet these requirements, the CMS detector plans to upgrade its data acquisition (DAQ) and trigger system. The Level-1 trigger system, with advanced hardware and modular, flexible algorithms, will handle the high bandwidth and processing demands of HL-LHC.

Dust-induced beam losses in the cryogenic arcs of the CERN Large Hadron Collider

A. Lechner, P. Belanger, I Efthymiopoulos, L. Grob, B. Lindstrom, R. Schmidt, D. Wollmann

Summary: This study investigates the interaction between the LHC proton beams and dust particles, which accounts for a significant amount of irregular beam loss events. By reconstructing key observables, the characteristics of beam-dust particle interactions are studied in the cryogenic arcs. The study shows that inelastic collision rates can reach high levels and result in substantial beam losses. The experimental distributions and their dependence on beam parameters can be quantitatively described by a simulation model assuming dust particles are attracted by the beam. The results provide important insights for predicting dust-induced beam losses in future runs of the High-Luminosity LHC.

An Analytical Approach to Calculate Soft Error Rate Induced by Atmospheric Neutrons

Frederic Wrobel, Ygor Aguiar, Cleiton Marques, Giuseppe Lerner, Ruben Garcia Alia, Frederic Saigne, Jerome Boch

Summary: In this study, an analytical model for predicting the soft error rate (SER) is proposed. The model separates the radiation-matter interaction from the geometry considerations, allowing the SER to be expressed as the sum of two contributions that can be calculated for any threshold linear energy transfer and any sensitive volume size. The proposed approach is validated by comparing it to Monte Carlo simulations, with good agreement despite approximations. Furthermore, the study shows that the contribution of neutrons in the 1-10 MeV energy range to the SER is expected to decrease for future down-sized technologies.
