An R&D; project has been recently started to consolidate the technology of resistive Micromegas for operations well beyond the actual operations at HEP experiments, aiming at stable, reliable, and high gain operation up to particle fluxes of the order of 10 MHz/cm2, over large surfaces. To cope with these challenges, readout copper pads, of a few mm2 size, have been proposed to reduce the occupancy of the readout elements, calling for innovative solutions for the spark protection resistive scheme.

An environmental monitoring and control system for the ATLAS ITk Outer Barrel quality control and integration
/ Alvarez, Diego (CERN) ; Joos, Hans L (CERN ; Gottingen U.) ; Kühn, Susanne (CERN) ; Pacifico, Nicola (CERN) ; Pettersen, Jarl N (CERN) ; Pons, Xavier (CERN) ; Vormwald, Benedikt (CERN)
This paper describes the development of a system based on Programmable Logic Controllers (PLC) for safety interlocking and environmental monitoring during ATLAS ITk Outer Barrel (OB) loaded local support quality control (QC) and later integration. The system has been developed at CERN with a focus on scalability, maintainability and reliability, and is expected to be deployed at the different ITk OB loading and integration sites..

ATLAS ITk tracking and readout performance
/ Bortoletto, D (Oxford U.)
/ATLAS ITK Collaboration
The ATLAS Inner Detector will be replaced with a new all-silicon Inner Tracker (ITk) designed for the challenging environment of the High Luminosity LHC (HL-LHC). The ITk layout of the pixel detector was recently successfully optimized to improve tracking performance and object reconstruction. [...]

Comparison of Two Detector Magnetic Systems for the Future Circular Hadron-Hadron Collider
/ Klyukhin, Vyacheslav (SINP, Moscow ; CERN) ; Ball, Austin (CERN) ; Berriaud, Christophe Paul (IRFU, Saclay) ; Curé, Benoit (CERN) ; Dudarev, Alexey (CERN) ; Gaddi, Andrea (CERN) ; Gerwig, Hubert (CERN) ; Hervé, Alain (Wisconsin U., Madison) ; Mentink, Matthias (CERN) ; Riegler, Werner (CERN) et al.
This work describes a detailed study of two possible options for the magnetic system of a Future Circular hadron-hadron Collider detector.The conceptual design study of a Future Circular hadron-hadron Collider (FCC-hh) to be constructed at CERN with a center-of-mass energy of the order of 100 TeV requires superconducting magnetic systems with a central magnetic flux density of an order of 4 T for the experimental detectors. The developed concept of the FCC-hh detector involves the use of an iron-free magnetic system consisting of three superconducting solenoids. [...]

Ab initio study of electronic states and radiative properties of the AcF molecule
/ Skripnikov, Leonid V (St. Petersburg, INP ; St. Petersburg State U.) ; Oleynichenko, Alexander V (St. Petersburg, INP) ; Zaitsevskii, Andréi (St. Petersburg, INP ; Moscow State U.) ; Mosyagin, Nikolai S (St. Petersburg, INP) ; Athanasakis-Kaklamanakis, Michail (CERN ; Leuven U.) ; Au, Mia (CERN) ; Neyens, Gerda (Leuven U.)
Relativistic coupled-cluster calculations of the ionization potential, dissociation energy, and excited electronic states under 35 000 cm−1 are presented for the actinium monofluoride (AcF) molecule. The ionization potential is calculated to be IPe = 48 866 cm−1, and the ground state is confirmed to be a closed-shell singlet and thus strongly sensitive to the T,P-violating nuclear Schiff moment of the Ac nucleus.

Measurements of binding energies and electromagnetic moments of silver isotopes – A complementary benchmark of density functional theory
/ de Groote, R P (Jyvaskyla U. ; Leuven U.) ; Nesterenko, D A (Jyvaskyla U.) ; Kankainen, A (Jyvaskyla U.) ; Bissell, M L (Manchester U.) ; Beliuskina, O (Jyvaskyla U.) ; Bonnard, J (York U., England ; IP2I, Lyon) ; Campbell, P (Manchester U.) ; Canete, L (Jyvaskyla U.) ; Cheal, B (Liverpool U.) ; Delafosse, C (Jyvaskyla U.) et al.
We report on a set of high-precision measurements of nuclear binding and excitation energies, as well as nuclear spins, magnetic dipole and electric quadrupole moments of neutron-rich silver isotopes, 113−123Ag. The measurements were performed using the JYFLTRAP mass spectrometer and the collinear laser spectroscopy beamline at the Ion Guide Isotope Separator On-Line (IGISOL) facility. [...]

Muography
/ Tanaka, Hiroyuki K M (Tokyo U.) ; Bozza, Cristiano (Salerno U.) ; Bross, Alan (Fermilab) ; Cantoni, Elena (INFN, Turin) ; Catalano, Osvaldo (IASF, Palermo) ; Cerretto, Giancarlo (INFN, Turin) ; Giammanco, Andrea (Louvain U.) ; Gluyas, Jon (Durham U.) ; Gnesi, Ivan (Enrico Fermi Ctr., Rome ; Frascati ; CERN) ; Holma, Marko (Oulu U.) et al.
Muography takes advantage of the specific properties of cosmic-ray
muons, relativistic leptons that are much heavier than electrons.
Cosmic-ray muons have strong penetrating power and a relativistic
nature, which means they can be used in a range of technologies,
including imagery; positioning, navigation, timing (PNT); and secured
communication in environments where conventional techniques are
unavailable. As cosmic-ray muons are universally present on Earth,
muographic measurements can be conducted in the same manner
across the globe. [...]
