Properties of Cosmic Lithium Isotopes Measured by the Alpha Magnetic Spectrometer / AMS Collaboration
We present the first measurement of cosmic-ray fluxes of  Li6 and  Li7 isotopes in the rigidity range from 1.9 to 25 GV. The measurements are based on 9.7×105  Li6 and 1.04×106  Li7 nuclei collected by the Alpha Magnetic Spectrometer on the International Space Station from May 2011 to October 2023. [...]

lpGBT: Low-Power Radiation-Hard Multipurpose High-Speed Transceiver ASIC for High-Energy Physics Experiments / Moreira, Paulo (CERN) ; Kulis, Szymon (CERN) ; Baron, Sophie (CERN) ; Biereigel, Stefan (CERN) ; Mendes, Eduardo Brandao De Souza (CERN) ; Matos-Carvalho, João P (New Lisbon U.) ; Faes, Bram (Leuven U.) ; Firlej, Miroslaw (AGH-UST, Cracow) ; Fiutowski, Tomasz (AGH-UST, Cracow) ; Fonseca, Jose (CERN) et al.
Commissioning of detector systems for the high-luminosity large Hadron collider (HL-LHC) is scheduled to take place between 2026 and 2028 at CERN. Application-specific integrated circuits (ASICs) for those systems have been in intense development over the past ten years. [...]

Solar Modulation of Cosmic Nuclei over a Solar Cycle: Results from the Alpha Magnetic Spectrometer / AMS Collaboration
We report the properties of precision time structures of cosmic nuclei He, Li, Be, B, C, N, and O fluxes over an 11-year solar cycle from May 2011 to November 2022 in the rigidity range from 1.92 to 60.3 GV. The nuclei fluxes show similar but not identical time variations with amplitudes decreasing with increasing rigidity. [...]

Properties of Cosmic Deuterons Measured by the Alpha Magnetic Spectrometer / AMS Collaboration
Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of the deuteron (D) flux are presented. The measurements are based on 21×106 D nuclei in the rigidity range from 1.9 to 21 GV collected from May 2011 to April 2021. [...]

Temporal Structures in Positron Spectra and Charge-Sign Effects in Galactic Cosmic Rays / AMS Collaboration
We present the precision measurements of 11 years of daily cosmic positron fluxes in the rigidity range from 1.00 to 41.9 GV based on 3.4×106 positrons collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The positron fluxes show distinctly different time variations from the electron fluxes at short and long timescales. [...]

Properties of Cosmic-Ray Sulfur and Determination of the Composition of Primary Cosmic-Ray Carbon, Neon, Magnesium, and Sulfur: Ten-Year Results from the Alpha Magnetic Spectrometer / AMS Collaboration
We report the properties of primary cosmic-ray sulfur (S) in the rigidity range 2.15 GV to 3.0 TV based on 0.38×106 sulfur nuclei collected by the Alpha Magnetic Spectrometer experiment (AMS). We observed that above 90 GV the rigidity dependence of the S flux is identical to the rigidity dependence of Ne-Mg-Si fluxes, which is different from the rigidity dependence of the He-C-O-Fe fluxes.

The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3 / ATLAS Collaboration
The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$ was routinely achieved at the start of fills, twice the design luminosity. [...]
