Summary: This work presents a novel optical method for selecting new liquid compounds for scintillation detectors based on evaluating their optical properties and defining emission yield parameters. It is a comparative method that allows the step-by-step selection of the best liquid scintillator among many through fluorescence and Ion Beam Induced Luminescence spectra analysis. The proposed method has successfully identified a new organic non-toxic and non-flammable liquid scintillator suitable for neutron detection.

Summary: A two-dimensional beam monitoring detector named pi(2) was developed and tested at the Bern University Hospital using an 18 MeV proton beam. The detector utilizes a scintillating compound coated onto a thin aluminium foil to capture the scintillating light produced when the beam passes through. The device has shown consistent performance and potential applications in cancer particle therapy, medical radioisotope production, and radiation hardness studies.

Summary: The luminescence behavior of ZnO crystals irradiated with 2 MeV H+ under different temperatures (300-100 K) was investigated using ion-beam-induced luminescence (IBIL). The results show that temperature and irradiation fluence have different effects on luminous intensity and peak position shift, and the emission bands in different temperature ranges have distinct origins and temperature dependencies.

Summary: The luminescent properties of CH3NH3PbBr3 single crystals, which are representative of the hybrid organic-inorganic lead perovskites that have been successfully applied in photovoltaics and currently investigated as potential nanosecond scintillators, are studied using the luminescent Z-scan technique with time resolution. A third harmonic of Ti-sapphire laser (& lambda; = 266 nm) with a pulse duration of 26 fs and 1 kHz frequency is used for luminescence excitation, creating charge carriers with densities ranging from 10(17) to 10(21) cm(-3) in temperatures ranging from 13 to 300 K. The temperature and excitation density dependence of the luminescence yield and kinetics are interpreted by considering temperature-dependent binding of electrons and holes, saturation of defects responsible for non-radiative relaxation, absorption saturation leading to increased penetration depth, and increased contribution of re-absorption.

Summary: In this study, a Cu+ and Al3+ co-doped ZnS scintillator was designed for X-ray detection. The prepared scintillator showed a high steady-state light yield (53,000 photons per MeV) upon X-ray irradiation, which is 5.3 times higher than that of the commercial Bi4Ge3O12 (BGO) scintillator. It was also employed as a scintillator to construct an indirect X-ray detector with superior spatial resolution and persistent stability under visible light interference.

Summary: This paper presents a novel analysis of cathodoluminescence (CL) and ion-beam induced luminescence (IBIL) based on virtual photon spectra (VPS) generated by charged particles passing luminescent species in wide band-gap ionic-covalent solids. The Weizsacker-Williams theory is employed for irradiations with a wide range of charged particle kinetic energy. It is found that the computed VPS decay rapidly regardless of particle energy and collision distance. The electron-energy dependence of experimental CL spectra and the variations of stopping power in experimental IBIL spectra are discussed in relation to the computed VPS.

Summary: Ion beam-induced luminescence (IBIL) spectroscopy based on the stark level characteristics of trivalent neodymium (Nd3+): 4F3/2 -> 4I9/2 emissions is a powerful tool for characterizing material molecules and crystal structures and quantifying radiation damage. The study found that a single IBIL spectrum carries as much information about the structure of a substance as the PL spectrum, and H+ does little damage to the sample in the course of analysis.

Summary: Ion beam induced luminescence (IBIL) analysis was performed to investigate the structures of Eu complexes in adsorbents used in extraction chromatography. The IBIL spectra of the Eu complexes showed differences depending on the extractants used. The differences are attributed to the different structures of the complexes. The luminescence of Eu complexes could be easily detected using a high linear energy transfer (LET) ion beam.

Summary: Luminescence nanothermometry is a technique that uses luminescence signals from nanosized materials to remotely and minimally invasively measure temperature. However, in a biomedical context, the reliability of temperature measurement is compromised by bias caused by environmental conditions. This study reveals an unexpected source of bias induced by metal ions, which enhances the emission of Ag2S nanothermometers. These findings highlight the need for caution when using luminescence nanothermometry in complex biological environments.

Summary: Conventional photonic crystals with a single period can enhance the light output of scintillators but often lead to spectrum distortion. This study introduces multi-size spherical nanostructures to efficiently outcouple scintillation light and reduce the wavelength dependence. The scintillators with these nanostructures exhibit noticeable enhancement in light output and weak wavelength dependence, making them suitable for various applications.

Summary: The second phase of the T2K experiment is set to begin in autumn 2022, featuring an upgrade to the Near Detector (ND280) with the construction of two new Time Projection Chambers called High-Angle TPC (HA-TPC). These TPCs will be equipped with eight Micromegas type charge readout modules on each endplate. The new Encapsulated Resistive Anode Micromegas detector, which combines resistive anode charge amplification with bulk-Micromegas technology, has been tested with successful results, meeting the requirements for the ND280 TPC upgrade.

Summary: This narrative review evaluates the use of nanoparticles (NPs) for delivering radionuclides to targets, focusing on systems tested in pre-clinical and clinical settings. A literature search retrieved data from significant studies, showing that all seven classes of nanoparticles have been extensively tested in clinical trials, but they have drawbacks. Liposomes are the only nanoparticles tested for clinical applications, but they have not been commercialized. Based on the current state, radiolabeled NPs require further investigation before finding their place in nuclear medicine.

Summary: This work presents a new approach to the problem of B(E2) values in Sn isotopes, focusing on the Sn-100 nucleus. The measurement of low-lying excited states in odd-even Sn isotopes provides valuable information for understanding nuclear structure. In this study, lifetime measurements were performed in Sn-105 using the Recoil Distance Doppler Shift technique. The results were compared with theoretical calculations and showed the importance of proton excitation in the Sn-100 core. The B(E2) of the core-coupled state demonstrates an enhanced staggering compared to even-mass Sn-104 and Sn-106 isotopes.

Summary: In this article, the authors investigate peripheral and semiperipheral reactions of 40,48Ca +40,48Ca at 35 MeV/nucleon. They use the VAMOS high acceptance spectrometer and the INDRA charged particle multidetector to obtain data. The measured isotopic composition of the projectile-like fragment (PLF) and the light charged particle (LCP) multiplicity are used to study isospin diffusion. The authors also reconstruct the initial quasiprojectile nuclei (QP) to observe the evolution of the isoscaling parameters.

Summary: We investigated the isospin equilibration process in the reactions Ni-58, Ni-64+Ni-58, Ni-64 at two different bombarding energies in the Fermi regime. Data acquired during the experimental campaign of the coupled INDRA-FAZIA apparatus in GANIL were used. The neutron content of the quasiprojectile residue and the light ejectiles from quasiprojectile evaporation were used as probes to study isospin diffusion between the projectile and target. Isospin transport ratio technique was employed and the relaxation of initial isospin imbalance with increasing centrality was observed. Isospin equilibration was found to be stronger in reactions at 32 MeV/nucleon compared to 52 MeV/nucleon.
