/ Bilko, Kacper (CERN ; Lab. Hubert Curien, St. Etienne) ; García Alía, Rubén (CERN) ; Costantino, Alessandra (ESTEC, Noordwijk) ; Coronetti, Andrea (CERN) ; Danzeca, Salvatore (CERN) ; Delrieux, Marc (CERN) ; Emriskova, Natalia (CERN) ; Fraser, Matthew Alexander (CERN) ; Girard, Sylvain (Lab. Hubert Curien, St. Etienne ; IUF, Paris) ; Johnson, Eliott Philippe (CERN) et al.
We present the progress related to CERN’s capacity of delivering highly penetrating, high-linear energy transfer (LET) heavy ions for radiation effect testing of electronic components within the CHARM High-energy Ions for Micro Electronics Reliability Assurance (CHIMERA) project. Profiting from the existing accelerator infrastructure, Monte Carlo simulations, and a 300- $\mu $ m-thick silicon diode, we highlight the beam characterization capabilities and a summary of the beam properties.

Fracture Toughness, Radiation Hardness, and Processibility of Polymers for Superconducting Magnets
/ Gaarud, Anders (CERN) ; Scheuerlein, Christian (CERN) ; Parragh, David Mate (CERN) ; Clement, Sébastien (CERN) ; Bertsch, Jacob (CERN) ; Urscheler, Cedric (CERN) ; Piccin, Roland (CERN) ; Ravotti, Federico (CERN) ; Pezzullo, Giuseppe (CERN) ; Lach, Ralf (Julich, Forschungszentrum)
High fracture toughness at cryogenic temperature and radiation hardness can be conflicting requirements for the resins for the impregnation of superconducting magnet coils. The fracture toughness of different epoxy-resin systems at room temperature (RT) and at 77 K was measured, and their toughness was compared with that determined for a polyurethane, polycarbonate (PC) and poly(methyl methacrylate) (PMMA).

We present a calibration of a commercial silicon diode with proton and alpha beams and gamma rays. The diode together with a fast acquisition chain can be exploited for both direct and indirect (through the secondary radiation field) beam characterization. [...]

CERN Proton Irradiation Facility (IRRAD) Data Management, Control and Monitoring System Infrastructure for post-LS2 Experiments
/ Gkotse, Blerina (CERN ; Paris, Ecole des Mines) ; Jouvelot, Pierre (Paris, Ecole des Mines) ; Pezzullo, Giuseppe (CERN) ; Ravotti, Federico (CERN)
Since upgrades of the CERN Large Hadron Collider are planned and design studies for a post-LHC particle accelerator are ongoing, it is key to ensure that the detectors and electronic components used in the CERN experiments and accelerators can withstand the high amount of radiation produced during particle collisions. To comply with this requirement, scientists perform radiation testing experiments, which consist in exposing these components to high levels of particle radiation to simulate the real operational conditions. [...]

Effect of Irradiation Temperature and Atmosphere on Aging of Epoxy Resins for Superconducting Magnets
/ Parragh, David Mate (CERN) ; Scheuerlein, Christian (CERN) ; Martin, Noémie (Lyon U.) ; Piccin, Roland (CERN) ; Ravotti, Federico (CERN) ; Pezzullo, Giuseppe (CERN) ; Koettig, Torsten (CERN) ; Lellinger, Dirk (Unlisted, DE)
The superconducting magnets of future particle accelerators will be exposed to high
irradiation doses at cryogenic temperatures. To investigate the effect of irradiation temperature
and atmosphere on the aging behavior, we have characterized the changes in thermomechanical
properties of six epoxy resins for potential use in superconducting magnets after irradiation up to
20 MGy in ambient air, inert gas, and liquid helium. [...]

Characterization of Lab-on-Fiber-based dosimeters in ultra-high dose radiation fields
/ Vaiano, Patrizio (Sannio U.) ; Quero, Giuseppe (Sannio U.) ; Fienga, Francesco (Naples U. ; CERN) ; Di Meo, Valentina (INFN, Naples) ; Casolaro, Pierluigi (Bern U., LHEP) ; Campajola, Luigi (INFN, Naples) ; Breglio, Giovanni (Naples U. ; CERN) ; Crescitelli, Alessio (INFN, Naples) ; Esposito, Emanuela (INFN, Naples) ; Cutolo, Antonello (Naples U.) et al.
Next generation High Energy Physics (HEP) accelerators will require new devices and technologies capable of
operating in extreme environments characterized by ultra-high radiation doses up to the MGy levels. To this aim, we report on an innovative Lab-On-Fiber (LOF) probe for the real-time dose monitoring. [...]

Nonresonant central exclusive production of charged-hadron pairs in proton-proton collisions at $\sqrt{s}$ = 13 TeV
/ CMS and TOTEM Collaboration
The central exclusive production of charged-hadron pairs in pp collisions at a centre-of-mass energy of 13 TeV is examined, based on data collected in a special high-$ \beta^* $ run of the LHC. The nonresonant continuum processes are studied with the invariant mass of the centrally produced two-pion system in the resonance-free region, $ m_{\pi^{+}\pi^{-}} < $ 0.7 GeV or $ m_{\pi^{+}\pi^{-}} > $ 1.8 GeV.

Absolute calibration of BSI monitors in the SPS North Area at CERN
/ Parsons França, Luana (CERN ; Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Welsch, Carsten (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Ahdida, Claudia (CERN) ; Ravotti, Federico (CERN) ; Roncarolo, Federico (CERN) ; Philippon, Florent (CERN) ; Pezzullo, Giuseppe (CERN) ; Zhang, H D (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Bernhard, Johannes (CERN) ; Van Dijk, Maarten (CERN) et al.
Developments in current and future experiments in the SPS North Area (NA) and PS East Area (EA) fixed target beam lines at CERN, including the “Physics Beyond Colliders” (PBC) program, require accurate determination of the number of protons on target (POT). The re-calibration of Beam Secondary Emission Intensity monitors (BSI), recently completed in one of the NA branches, reduced the estimated uncertainty on the absolute POT to a few percent. [...]
