Summary: This paper reports results on the measurement of the cosmic-ray composition using the TALE air fluorescence detector, focusing on X-max distributions of showers observed over a wide energy range. The study shows that the composition of cosmic rays becomes heavier with increasing energy, consistent with a rigidity-dependent cutoff of events from Galactic sources. Additionally, a change in the cosmic-ray composition is observed at energies just above 10(17) eV.

Summary: This study shows that the 3D trench-type pixels developed by the TimeSPOT Collaboration achieve a time resolution close to 10 ps and a detection efficiency close to 100% at high instantaneous luminosities. A simple leading-edge discriminating technique can be used to achieve a time resolution as good as 25 ps without any amplitude correction. These 3D trench-type pixels are the fastest charged-particle pixel detectors available and offer a promising solution for the future upgrade of tracking systems in extreme conditions.

Summary: We report measurements of the angular distributions of low momentum atmospheric muons at 38 m above sea level for zenith angles between -60 and 60 degrees in the south-north direction. The muon detection was performed using two NaI(Tl) scintillation detectors mounted in coincidence. The integrated and differential muon flux were determined by analyzing the deposited energy spectra in the scintillators backed up by a Geant4 simulation of the experimental setup. The results are consistent with the cosn(0) distribution and fill the gap in the geomagnetic cutoff rigidity interval 8 GV < Pc < 14 GV where no similar measurements were performed before. We found that n = 1.88 - 0.12 P mu c in the domain of muon momentum cutoff P mu c < 1 GeV/c. These measurements are useful for muon studies requiring accurate integrated flux.

Summary: The response of Timepix3 detectors with HR GaAs:Cr sensors of different thicknesses was studied through particle beam irradiation. Precise measurements of time and energy allowed for the determination of charge carrier transport properties. By analyzing the tracks left by charged particles hitting the sensor, properties such as charge collection efficiency and carrier drift velocity were determined. Results were implemented into simulation frameworks and validated through comparison with measurement data from a gamma-ray source.

Summary: Measurements of muon zenith angle distributions and vertical flux using a portable setup of liquid scintillator bars are reported in this study. Energy deposition and timing of scintillators are utilized to construct two dimensional tracks for charged particles and obtain their angles. The analysis method is improved to obtain a clean muon spectrum. The study also suggests that a setup of three bars can be used for quicker and more precise measurements.

Summary: Carbon ion radiotherapy, which utilizes C-12 ions to treat deep-seated tumors, offers advantages such as high dose release consistency, high relative biological effectiveness, and low oxygen enhancement ratio. The development of an online range verification system is needed to fully utilize the precision in delivering the dose to the target volume. There is ongoing exploration of using charged secondary fragments for monitoring, which shows promise in clinical trials.

Summary: In this study, we present the direct measurement from space of solar particles emitted during the solar event on October 28, 2021. The observations provide information on the characteristics of the event, such as the proton flux and energy spectrum. The data analysis suggests that particles may have been accelerated through stochastic acceleration at the coronal mass ejection-driven shock. The findings contribute to our understanding of particle acceleration and can be used for Space Weather purposes.

Summary: This paper presents the CAESAR project, which aims to tackle the relevant aspects of Space Weather (SWE) science and develop a prototype of the scientific data centre for Space Weather of the Italian Space Agency (ASI) called ASPIS. The project involves 10 Italian institutions as partners and a total of 92 researchers, investigating the whole chain of phenomena from the Sun to Earth up to planetary environments in a multidisciplinary and comprehensive way. The ASPIS prototype will unify multiple SWE resources through a flexible and adaptable architecture, integrating currently available international SWE assets to advance forecasting capabilities.

Summary: Time-dependent energy spectra of galactic cosmic rays are heavily affected by the solar wind and the solar magnetic field, resulting in a phenomenon called solar modulation. This paper presents the first spectra of galactic protons measured by the HEPD-01 instrument on the CSES-01 satellite from 2018 to 2022, providing valuable information for understanding the propagation of cosmic rays in the heliosphere.

Summary: High-energy, long gamma-ray bursts (GRBs) can be exceptionally bright when they happen in the close-by universe, such as the recent GRB221009A with a redshift of 0.152. This event, observed by many gamma-ray space experiments, was accompanied by sudden electron flux changes measured by the HEPP-L charged particle detector on a satellite orbiting over Europe. The observed electron flux closely matched the time dependence of the photon flux associated with the main emission of the GRB.

Summary: We present precision measurements of 11 years of daily cosmic electron fluxes collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The electron fluxes exhibit variations on multiple timescales, including recurrent variations with periods of 27 days, 13.5 days, and 9 days. Interestingly, a hysteresis between electron and proton fluxes is observed at rigidities below 8.5 GV, indicating distinct time variations. This continuous electron data provides valuable insights into the charge sign dependence of cosmic rays over an 11-year solar cycle.

Summary: This study presents the properties of primary cosmic-ray sulfur (S) in the rigidity range of 2.15 GV to 3.0 TV, based on data collected by the Alpha Magnetic Spectrometer experiment. The rigidity dependence of the S flux is similar to that of Ne-Mg-Si fluxes above 90 GV, but different from He-C-O-Fe fluxes. The traditional primary cosmic rays S, Ne, Mg, and C show significant secondary components, and their fluxes can be described by the sum of primary silicon or oxygen fluxes and secondary fluorine or boron fluxes, respectively.

Summary: We present precise measurements of daily cosmic positron fluxes over 11 years in the rigidity range from 1.00 to 41.9 GV using data collected by the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The electron and positron fluxes show distinct time variations at short and long timescales, with a hysteresis observed between the two at rigidities below 8.5 GV. On the other hand, the positron and proton fluxes exhibit similar time variations, but the positron fluxes are found to be modulated more significantly than the proton fluxes for rigidities below 7 GV. These continuous daily positron fluxes, along with other cosmic ray measurements, provide valuable insights into the charge-sign and mass dependencies of cosmic rays in the heliosphere.

Summary: The hadron particle identification provided by LHCb's RICH system is crucial for the success of the experiment, and it will continue to play a significant role in Upgrade II. To maintain the current excellent particle identification performance, substantial improvements in the precision of measuring the space and time coordinates of detected photons in the RICH and in the resolution of the reconstructed Cherenkov angle are required.

Summary: Thermal and cold neutron beamlines require detector systems with high efficiency, large active area, and good spatial resolution. This study presents a new design of Anger camera using silicon photomultipliers (SiPMs) instead of photomultiplier tubes (PMTs), offering better resolution, less distortion, and more compactness. The use of SiPMs also enables the camera to be used in strong magnetic fields, providing additional experimental capabilities.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
