Summary: A position-sensitive detector for alpha-rays based on an OLS fiber and SiPM readout was developed for detecting alpha contamination and locating it in nuclear plants and radiation facilities. The detector showed enhanced capability for alpha-ray measurements compared to conventional scintillating fibers. By employing the time-difference method, the detector achieved one-dimensional measurement of radiation distribution along the fiber with time and spatial resolutions of approximately 3.6 ns and 290 mm FWHM, respectively. The resolving capability of the measurement system to distinguish two sources was found to be less than 300 mm.

Summary: The article describes a set-up involving a large-area MCP detector for detecting high-energy particles by producing a shower of secondary electrons. The ions pass through a collimator and conversion foil in the detector to generate secondary electrons before being detected after reflection. The MCP has been tested with strontium-90 and Th-232 for its low cost and fast fall time constant, making it suitable for low-energy electron detection with high timing resolution.

Summary: This study developed a biomimetic porous fibre bundle adsorbent with multiple adsorption sites by combining coconut shell biochar with amino and sulfhydryl group-functionalized cellulose nanofibre bundles. The high porosity and specific surface area of the adsorbent effectively improved mass transfer kinetics and allowed for synchronous removal of various heavy metal ions. The adsorbent was able to remove low concentrations of Pb(II), Cu(II), Cd(II), and Cr(VI) to safe drinking water level standard concentrations within 20 minutes.

Summary: The proton drip-line nucleus Ne-17 has been experimentally investigated to determine its two-proton halo character. The experimental results suggest that Ne-17 may only have a relatively modest halo character. The quantitative consistency between the theoretical calculations and experimental data, supported by the independence in distinguishing different knockout processes, provides valuable information on the contributions of valence-proton knockout and knockout from the O-15 core.

Summary: The atomic masses of 55Sc, 56'58Ti, and 56-59V have been measured using a high-precision multireflection time-of-flight technique. By reducing the mass uncertainties, the study sheds new light on the N = 34 shell effect in Ti and V isotopes. The results indicate the nonexistence of the N = 34 empirical two-neutron shell gaps for Ti and V and identify an enhanced energy gap unique to Ca.

Summary: Unbound states in 17C were studied by removing one neutron from an 18C beam at an energy of 245 MeV/nucleon on a carbon target. The energy spectrum of 17C above the single-neutron decay threshold was reconstructed using invariant mass spectroscopy, revealing resonances at 0.52(2), 0.77(2), 1.36(1), 1.91(1), 2.22(3), and 3.20(1) MeV. Through comparisons with calculations, the resonance at 0.77(2) MeV was tentatively assigned as the second 5/2+ state, while the resonances at 1.91(1) and 3.20(1) MeV were identified as p-shell hole states with spin-parities 1/2-1 and 3/2-1, respectively. A YSOX shell-model Hamiltonian based on the monopole-based universal interaction provided a good description of the results.

Summary: Subjecting a physical system to extreme conditions is a common method to gain a better understanding of its organization and structure. The investigation of isotopes with different neutron-to-proton ratios than stable nuclei is an important test for nuclear-structure theories. This study reports the first observation of the decay of O-28 and 27O isotopes and compares their decay energies with theoretical models. The results have implications for the understanding of nuclear structure.

Summary: The 9Be(25F(5/2+), 24O)X proton-removal reaction was studied, and it was found that the proton d5/2 strength in the ground-state to ground-state transition is significantly depleted compared to shell-model expectations. The experimental data can be well explained within the framework of the Particle-Vibration Coupling (PVC) model, suggesting the presence of a quadrupole phonon in the effective 24O* core.

Summary: This study investigates the contributions of various reaction channels to the interaction, reaction, charge-changing, and neutron-changing cross sections, aiming to explore the relation between microscopic interactions and the symmetry energy component of the equation of state (EoS) relevant to neutron star structures. Comparisons are made between neutron skins extracted from diverse experimental techniques and those obtained through Hartree-Fock-Bogoliubov calculations and density-dependent interactions used in the relativistic mean-field method. The study concludes that no definitive conclusion can be drawn about the best EoS due to the wide range of uncertainty in the experimental data. Additionally, the study explores the prospects of using neutron-changing reactions to assess the isospin dependence of the neutron skin in neutron-rich nuclei.

Summary: Experimental information on fragment emissions is important for understanding nuclear collision dynamics and developing transport models. The hypothesis of thermal equilibrium breaks down for particles emitted with high transfer momentum. The scaling features of particle yield ratios from two systems are examined to investigate the system's properties, and the breakdown of isoscaling for high transverse momentum particles cannot be explained by the antisymmetrized molecular dynamics model.

Summary: The study predicts the A = 6 nuclear level scheme based on chiral effective field theory (chi EFT), finding slight underbinding of He-6 and Li-6, consistent with experimental data within theoretical error bars. By considering correlated chi EFT-truncation errors, more precise predictions are obtained for separation energies, suggesting potential further reduction of error bars by extending the model space used by JUPITERNCSM.

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: 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.
