Irradiation aging of the CMS Drift Tube muon detector / Ferrero, D.D. Redondo ; Abbiendi, G. ; Maestre, J. Alcaraz ; Fernández, A. Álvarez ; González, B. Álvarez ; Amapane, N. ; Bachiller, I. ; Barcala, J.M. ; Barcellan, L. ; Battilana, C. et al.
During the High Luminosity LHC, the Drift Tube chambers installed in the CMS detector need to operate with an integrated dose ten times higher than expected at the LHC due to the increase in integrated luminosity from 300 fb${-1}$ to 3000 fb$^{-1}$. Irradiations have been performed to assess the performance of the detector under such conditions and to characterize the radiation aging of the detector. [...]

Intercomparison of personal and ambient dosimeters in extremely high-dose-rate pulsed photon fields / Zorloni, Gabriele (Milan Polyech.) ; Ambrožová, Iva (Prague, Nucl. Phys. Inst.) ; Carbonez, Pierre (CERN) ; Caresana, Marco (Milan Polytech.) ; Ebert, Stephan (VKTA, Dresden) ; Olšovcová, Veronika (ELI Beamlines, Dolní Břežany) ; Pitzschke, Andreas (Centr. Hosp. U. Vaudois, Lausanne) ; Ploc, Ondrej (Prague, Nucl. Phys. Inst.) ; Pozzi, Fabio (CERN) ; Silari, Marco (CERN) et al.
Recent advances in laser driven accelerators boosted the development of high dose-rate fast pulsed systems all over the world. The stray radiation comprises primarily high-energy photons, resulting in extremely high dose rates within pico-/femto-second pulses. [...]

A 410 MHz resonant cavity pickup for heavy ion storage rings / Sanjari, M S (Darmstadt, GSI) ; Dmytriiev, D (Darmstadt, GSI ; U. Heidelberg (main)) ; Litvinov, Yu A (Darmstadt, GSI ; U.

An improved design of a longitudinally sensitive resonant Schottky cavity pickup for the heavy ion storage rings of the Facility for Antiproton and Ion Research in Europe (FAIR) project is reported. The new detector has a higher measured Q value of ∼3000 and a higher simulated shunt impedance of 473.3 kΩ. [...]

BioDynaMo: a modular platform for high-performance agent-based simulation / Breitwieser, Lukas (CERN ; Zurich, ETH) ; Hesam, Ahmad (CERN ; Zurich, ETH) ; de Montigny, Jean (CERN) ; Vavourakis, Vasileios (Cyprus U. ; University Coll. London) ; Iosif, Alexandros (Cyprus U.) ; Jennings, Jack (Newcastle upon Tyne U.) ; Kaiser, Marcus (Newcastle upon Tyne U. ; Shanghai SSRF ; Nottingham U.) ; Manca, Marco (Unlisted, NL) ; Di Meglio, Alberto (CERN) ; Al-Ars, Zaid (Delft Tech. U.) et al.
Motivation: Agent-based modeling is an indispensable tool for studying complex biological systems. However, existing simulation platforms do not always take full advantage of modern hardware and often have a field-specific software design. Results: We present a novel simulation platform called BioDynaMo that alleviates both of these problems. BioDynaMo features a modular and high-performance simulation engine. [...]

Application of Hot Press Bending for Shaping a Stack of HTS Tapes Operating as a Trapped Flux Magnet / Tomkow, Lukasz (Cambridge U. ; CERN) ; Smara, Anis (Cambridge U.) ; Glowacki, Bartek A (Cambridge U. ; Inst. Power Eng., Warsaw)
Trapped-flux magnets made of stacks of superconducting tapes are an interesting and important alternative to the application of rare-earth permanent magnets and trapping flux in bulk superconductors. Many applications, such as electric motors, can require the complex shapes of magnetic elements to combat issues such as demagnetization during the operation. [...]

Gas mixture quality studies for the CMS RPC detectors during LHC Run 2 / Gelmi, A (INFN, Bari ; Bari U.) ; Guida, R (CERN) ; Mandelli, B (CERN) /CMS Muon Group Collaboration
Resistive Plate Chamber (RPC) detectors are widely employed in the muon trigger systems of three experiments at the CERN Large Hadron Collider (LHC). They are operated with gas mixture recirculation systems to reduce operational costs and greenhouse gas emissions since their gas mixture is based on C2H2F4, which has a high global warning potential. [...]

Neopterin formation through radical scavenging of superoxide by the macrophage synthesised antioxidant 7,8-dihydroneopterin / Baxter-Parker, Gregory (Canterbury U.) ; Prebble, Hannah M (Canterbury U.) ; Cross, Sean (Canterbury U.) ; Steyn, Nina (Canterbury U.) ; Shchepetkina, Anastasia (Canterbury U.) ; Hock, Barry D (Otago U.) ; Cousins, Andrew (Unlisted, NZ) ; Gieseg, Steven P (CERN)
Clinical measurement of neopterin has been extensively used as a marker of inflammation but the in vivo mechanism generating neopterin is poorly understood. Neopterin is described as the oxidation product of 7,8-dihydroneopterin, a potent antioxidant generated by monocyte/macrophages in response to interferon-γ. [...]

Measurements of the $^{33}$S$ ($n$, α)$^{30}$ $Si$ cross-section at n_TOF and ILL: Implications in neutron capture therapy / Praena, Javier (Granada U.) ; Isabelópez-Casas, L (Granada U.) ; Sabat, Mariaé-Gilarte (CERN ; Seville U.) ; Arias, Fernando de Saavedra (Granada U.) ; Porras, Ignacio (Granada U.)
Up to a couple of years ago, the 33S(n, α)30Si cross-section data had been limited and scarce. The origin in the solar system of 36S had been the only motivation to study that cross-section. [...]

Purpose To evaluate the quantitative imaging performance of a spectral photon-counting computed tomography (SPCCT) scanner for radiotherapy applications. An experimental comparison of the quantitative performance of a Siemens dual-energy CT (DECT) and a MARS SPCCT scanner is performed to estimate physical properties relevant to radiotherapy of human substitute materials and contrast agent solutions.

Secondary electron generation mechanisms in carbon allotropes at low impact electron energies / Bellissimo, Alessandra (Rome U. ; CERN) ; Pierantozzi, Gian Marco (Rome U.) ; Ruocco, Alessandro (Rome U.) ; Stefani, Giovanni (Rome U.) ; Ridzel, Olga Yu (TU Vienna) ; Astašauskas, Vytautas (TU Vienna) ; Werner, Wolfgang S M (TU Vienna) ; Taborelli, Mauro (CERN)
More than a century after the discovery of the electron, there are still fundamental, yet unresolved, questions concerning the generation-ejection mechanism of the ubiquitous Secondary Electrons (SEs) from a solid surface. Broadness of the field of application for these SEs makes it desirable to be able to control this phenomenon, which requires the understanding of the elementary physical mechanism leading to their generation and emission. This paper reports on the dissection of such a tangled process operated by the help of spectroscopic tools of increasing finesse; measuring differential cross sections with an increasing degree of differentiation. These results demonstrate that single ionising scattering events, assisted by collective excitations, constitute the fundamental ingredient leading to SE-generation and -emission. [...]
