A method that enables visualization of lateral distribution of Li in thin films is described. The method is based on the simultaneous detection of the reaction products of the Li(n,α)t nuclear reaction with thermal neutrons measured with two multipixel detectors in a sandwich geometry with a sample. Here, the principle and basic methodological parameters of the method, including tests with thin polymers with known Li microstructure, are discussed.

Article Synopsis
  • * Liquid scintillators are typically used for beta-ray detection, but they can be complicated in field settings, prompting an exploration of the GSENSE2020BSI back-illuminated sCMOS imager for on-site detection instead.
  • * Testing with a tritium radiation source showed that the sCMOS imager could effectively identify beta-ray patterns and quantify tritium contamination as low as 10 Bq/cm in 100 seconds, reinforcing its viability for practical use.

Hard x-ray imaging is indispensable across diverse fields owing to its high penetrability. However, the resolution of traditional x-ray imaging modalities, such as computed tomography (CT) systems, is constrained by factors including beam properties, the limitations of optical components, and detection resolution. As a result, the typical resolution in commercial imaging systems that provide full-field imaging is limited to a few hundred microns, and scanning CT systems are too slow for many applications.

Medical applications of radiation have been widely spread until now. However, the exposure of medical staff is sometimes overlooked, because treatment of patients is the first priority. The purpose of this study is to develop a small and light monitor that can measure the energy spectrum and dose of gamma-rays at the same time in real-time for medical applications.

Article Synopsis
  • Scientists created a new type of detector for positron emission tomography (PET) scanners that makes it easier to find where gamma photons interact.
  • The new design mixes different types of sensors to improve the way these interactions are measured without needing complicated instructions.
  • Tests showed that this hybrid detector can accurately identify the positions of events and has fast timing, making it more efficient and easier to use than older models.

We report the development of a high-sensitivity and high-resolution PET subsystem for a next-generation preclinical PET/EPR hybrid scanner for investigating and improving hypoxia imaging with PET. The PET subsystem consists of 14 detector modules (DM) installed within a cylindrical supporting frame whose outer and inner diameters are 115mm and 60mm, respectively. Each DM contains eight detector units (DU) in a row and each DU is made of a 12×12 array of 1×1×10mm LYSO crystals (with a 1.
