New optics design of the Cherenkov threshold detectors at CERN
/ Buesa Orgaz, Jan (CERN) ; Schwinzerl, Martin (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Folch, Ramon (CERN) ; Göktürk, Berare (CERN) ; Kadi, Yacine (CERN) ; Nevay, Laurence (CERN) ; Ortega Ruiz, Inaki (CERN) et al.
The performance of the Cherenkov threshold detectors (XCET) used in the secondary beam areas (SBA) at CERN is limited by their built-in optics. This study showcases an improved design using compound parabolic concentrators (CPCs) to reduce size and cost of the optics while optimizing the light collection efficiency. [...]

Findings of the Physics Beyond Colliders ECN3 Beam Delivery Task Force
/ Ahdida, Claudia (CERN) ; Bartosik, Hannes (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Calviani, Marco (CERN) ; Colinet, Antoine (CERN) ; Esposito, Luigi Salvatore (CERN) ; Franqueira Ximenes, Rui (CERN) ; Fraser, Matthew Alexander (CERN) ; Gautheron, Fabrice (University of Patras (GR)) et al.
The ECN3 Beam Delivery Task Force was mandated by the PBC Study Group to assess the technical feasibility of increasing the proton beam intensity to the ECN3 hall of the North Area to satisfy the demands of a compelling set of PBC experimental physics proposals. This report summarises the findings of the Task Force that converge on a technically feasible solution with an implementation timeline that could exploit and build upon the investment already foreseen as part of Phase 1 of the NA-CONS project, and take the SPS complex into a new intensity frontier for Fixed Target physics in Run4..

Dynamic Response of Graphitic Targets with Tantalum Cores Impacted by Pulsed 440-GeV Proton Beams
/ Simon, Pascal (Darmstadt, GSI ; Darmstadt, Tech. U.) ; Drechsel, Philipp (Darmstadt, GSI ; Darmstadt, Tech. U.) ; Katrik, Peter (Darmstadt, Tech. U.) ; Voss, Kay-Obbe (Darmstadt, Tech. U.) ; Bolz, Philipp (Darmstadt, Tech. U. ; Darmstadt, GSI) ; Harden, Fiona J (CERN) ; Guinchard, Michael (CERN) ; Kadi, Yacine (CERN) ; Trautmann, Christina (Darmstadt, GSI ; Darmstadt, Tech. U.) ; Tomut, Marilena (Darmstadt, GSI)
Various graphite targets with a tantalum core were exposed to 440 GeV pulsed proton beams at the HiRadMat facility at CERN.
)e dynamic response was investigated by monitoring the surface velocity of the samples by laser Doppler vibrometry. )e study
comprises different graphite grades, such as polycrystalline, expanded and carbon-fiber reinforced graphite, and low-density
graphitic foams, all candidates for beam-intercepting devices in high-power accelerators. [...]

Combined Temperature Radiation Effects and Influence of Drawing Conditions on Phosphorous‐Doped Optical Fibers
/ Di Francesca, Diego (CERN) ; Girard, Sylvain (Lyon U. ; Lab. Hubert Curien, St. Etienne) ; Agnello, Simonpietro (Palermo U.) ; Alessi, Antonino (Lyon U. ; Lab. Hubert Curien, St. Etienne) ; Marcandella, Claude (CEA DAM) ; Paillet, Philippe (CEA DAM) ; Ouerdane, Youcef (Lyon U. ; Lab. Hubert Curien, St. Etienne) ; Kadi, Yacine (CERN) ; Brugger, Markus (CERN) ; Boukenter, Aziz (Lyon U. ; Lab. Hubert Curien, St. Etienne)
This work focuses on the effects of high dose ionizing radiation, up to 10 MGy(SiO$_2$), on P-doped multimode optical fibers (OF) at different irradiation temperatures. The investigation is based on two complementary experimental techniques: radiation-induced attenuation (RIA) measurements and electron paramagnetic resonance (EPR). [...]

Temperature Effect on the Radioluminescence of Cu-, Ce-, and CuCe-Doped Silica-Based Fiber Materials
/ Kerboub, Nourdine (CERN ; HCL, Lyon ; CNES, Toulouse) ; Di Francesca, Diego (CERN ; HCL, Lyon) ; Girard, Sylvain (HCL, Lyon) ; Morana, Adriana (Lyon, Ecole Centrale) ; El Hamzaoui, Hicham (Lille U.) ; Ouerdane, Youcef (HCL, Lyon) ; Bouwmans, Géraud (Lille U.) ; Habert, Rémi (Lille U.) ; Boukenter, Aziz (HCL, Lyon) ; Capoen, Bruno (Lille U.) et al.
We evaluate the temperature effect on the X-ray radiation-induced luminescence (RIL) of Cu- or Ce-single-doped and CuCe-codoped silica glass. Previous investigations showed that these optical materials exhibit interesting dosimetry properties, such as very good detection capabilities and linear response over a large range of dose rate.
