Pair Spectrometer for FACET-II
/ Naranjo, Brian (UCLA) ; Andonian, Gerard (UCLA) ; Cavanagh, Niall (Queen's U., Belfast) ; Di Piazza, Antonino (Heidelberg, Max Planck Inst.) ; Fukasawa, Atsushi (UCLA) ; Gerstmayr, Elias (SLAC) ; Holtzapple, Robert (Cal. Poly.) ; Keitel, Christoph (Heidelberg, Max Planck Inst.) ; Majernik, Nathan (UCLA) ; Meuren, Sebastian (SLAC) et al.
We present the design of a pair spectrometer for use at FACET-II, where there is a need for spectroscopy of photons having energies up to 10 GeV. Incoming gammas are converted to high-energy positron-electron pairs, which are then subsequently analyzed in a dipole magnet. [...]

M2 Experimental Beamline Optics Studies for Next Generation Muon Beam Experiments at CERN
/ Banerjee, Dipanwita (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; D'Alessandro, Gian Luigi (CERN ; JAI, UK) ; Gatignon, Laurent (CERN) ; Gerbershagen, Alexander (CERN) ; Montbarbon, Eva (CERN) ; Mussolini, Carlo Alberto (CERN ; JAI, UK) ; Parozzi, Elisabetta (CERN ; Milan Bicocca U. ; INFN, Milan Bicocca) et al.
In the context of the Physics Beyond Colliders Project, various new experiments have been proposed for the M2 beamline at the CERN North Area fixed target experimental facility. The experiments include MUonE, NA64µ, and the successor to the COMPASS experiment, tentatively named AMBER/NA66. [...]

New Generation CERN LHC Injection Dump - Assembly and Installation (TDIS)
/ Carbajo Perez, David (CERN) ; Berthomé, Emmanuel (CERN) ; Bertone, Caterina (CERN) ; Biancacci, Nicolo (CERN) ; Bracco, Chiara (CERN) ; Bregliozzi, Giuseppe (CERN) ; Bulat, Bartosz (CERN) ; Cadiou, Cyril (CERN) ; Calviani, Marco (CERN) ; Cattenoz, Gregory (CERN) et al.
During CERN’s LS2, several upgrades were performed to beam intercepting devices in the framework of the HL-LHC Project. Upgraded equipment includes two internal beam dumps (TDIS) intended for machine protection located at the injection points from the SPS to the LHC. [...]

Flow and fracture of austenitic stainless steels at cryogenic temperatures
/ Fernández-Pisón, P (CERN ; Carlos III U., Madrid) ; Rodríguez-Martínez, J A (Carlos III U., Madrid) ; García-Tabarés, E (CERN ; Carlos III U., Madrid) ; Avilés-Santillana, I (CERN) ; Sgobba, S (CERN)
In this paper, we have characterized the microstructural evolution and the plastic flow and fracture behaviours of AISI 304L and AISI 316LN stainless steel grades at liquid nitrogen temperature (4 K) and at liquid helium temperature (77 K). Uninterrupted tensile experiments, where the sample is continuously deformed under quasi-static loading conditions until fracture, have been carried out with a Single-Section Sample to obtain the stress–strain characteristics of the two grades.

ROMULUSLib: An Autonomous, TCP/IP-Based, Multi-Architecture C Networking Library for DAQ and Control Applications
/ Yadav, Amitabh (CERN) ; Boukabache, Hamza (CERN) ; Ceesay-Seitz, Katharina (CERN) ; Gerber, Nicola (CERN ; CSEM, Neuchatel) ; Perrin, Daniel (CERN)
The new generation of Radiation Monitoring electronics developed at CERN, called the CERN RadiatiOn Monitoring Electronics (CROME), is a Zynq-7000 SoC-based Data Acquisition and Control system that replaces the previous generation to offer a higher safety standard, flexible integration and parallel communication with devices installed throughout the CERN complex. A TCP/IP protocol based C networking library, ROMULUSlib, was developed that forms the interface between CROME and the SCADA supervision software through the ROMULUS protocol. [...]

Identification of Critical Components in the Complex Technical Infrastructure of the Large Hadron Collider Using Relief Feature Ranking and Support Vector Machines
/ Shokry, Ahmed (Ec. Polytech., Palaiseau (main)) ; Baraldi, Piero (Milan, Polytech.) ; Castellano, Andrea (Milan, Polytech.) ; Serio, Luigi (CERN) ; Zio, Enrico (Milan, Polytech. ; U. PSL)
This work proposes a data-driven methodology for identifying critical components in
Complex Technical Infrastructures (CTIs), for which the functional logic and/or the system structure
functions are not known due the CTI’s complexity and evolving nature. The methodology uses large
amounts of CTI monitoring data acquired over long periods of time and under different operating
conditions. [...]
