Practical Aspects of Calibration of Airborne Particle Counters According to ISO 21501-4 Standard
The article reviews the practical aspects of calibration of airborne particle counters according to GOST R ISO 21501-4 (Russian equivalent of the international ISO 21501-4) standard. The authors share their gained experience and explain what difficulties can be faced during the procedure described in the standard, how to avoid and how to revise them. The article may be useful for specialists as an introduction to the standard or for particle counters’ users who want to learn more about practical metrology aspects of these devices without going into the specifics and the basis.

Preface
The eleventh international symposium on “Large TPCs for low-energy rare event detection” was held in Paris from 11th to 13th of December 2023 in a new venue at the historical center of Paris: University Paris Cité. The symposium was attended by 86 participants.As in previous events the program included neutrino physics, dark matter and axion searches, related detector R&D and theoretical aspects.It was the time to celebrate the 50th anniversary of the idea of the TPC. David Nygren shared his memories of the invention and development of the Time Projection Chamber. Diego Gonzalez Diaz imagined what could be the next 50 years of TPCs, and Jaime Dawson presented DUNE, the largest TPC under construction.List of Organizing Committee and Advisory Committee are available in this PDF.

Real-time single-proton counting with transmissive perovskite nanocrystal scintillators
High-sensitivity radiation detectors for energetic particles are essential for advanced applications in particle physics, astronomy and cancer therapy. Current particle detectors use bulk crystals, and thin-film organic scintillators have low light yields and limited radiation tolerance. Here we present transmissive thin scintillators made from CsPbBr

nanocrystals, designed for real-time single-proton counting. These perovskite scintillators exhibit exceptional sensitivity, with a high light yield (~100,000 photons per MeV) when subjected to proton beams. This enhanced sensitivity is attributed to radiative emission from biexcitons generated through proton-induced upconversion and impact ionization. These scintillators can detect as few as seven protons per second, a sensitivity level far below the rates encountered in clinical settings. The combination of rapid response (~336 ps) and pronounced ionostability enables diverse applications, including single-proton tracing, patterned irradiation and super-resolution proton imaging. These advancements have the potential to improve proton dosimetry in proton therapy and radiography.
Current organic proton detectors have poor detection sensitivities due to low light yields and limited radiation toleration. Here the authors report a perovskite nanocrystal-based transmissive thin scintillator that can detect seven protons per second, enabled by radiative emission from biexcitons.

Radiation Dose Reconstruction for Epidemiologic Uses
Growing public concern about releases of radiation into the environment has focused attention on the measurement of exposure of people living near nuclear weapons production facilities or in areas affected by accidental releases of radiation.
Radiation-Dose Reconstruction for Epidemiologic Uses responds to the need for criteria for dose reconstruction studies, particularly if the doses are to be useful in epidemiology. This book provides specific and practical recommendations for whether, when, and how studies should be conducted, with an emphasis on public participation.
Based on the expertise of scientists involved in dozens of dose reconstruction projects, this volume:
Provides an overview of the basic requirements and technical aspects of dose reconstruction.
Presents lessons to be learned from dose reconstructions after Chernobyl, Three Mile Island, and elsewhere.
Explores the potential benefits and limitations of biological markers.
Discusses how to establish the \"source term\"-that is, to determine what was released.
Explores methods for identifying the environmental pathways by which radiation reaches the body.
Offers details on three major categories of dose assessment.

Inorganic scintillating materials and scintillation detectors
Scintillation materials and detectors that are used in many applications, such as medical imaging, security, oil-logging, high energy physics and non-destructive inspection, are reviewed. The fundamental physics understood today is explained, and common scintillators and scintillation detectors are introduced. The properties explained here are light yield, energy non-proportionality, emission wavelength, energy resolution, decay time, effective atomic number and timing resolution. For further understanding, the emission mechanisms of scintillator materials are also introduced. Furthermore, unresolved problems in scintillation phenomenon are considered, and my recent interpretations are discussed. These topics include positive hysteresis, the co-doping of non-luminescent ions, the introduction of an aimed impurity phase, the excitation density effect and the complementary relationship between scintillators and storage phosphors.

The Jupiter Energetic Particle Detector Instrument (JEDI) Investigation for the Juno Mission
The Jupiter Energetic Particle Detector Instruments (JEDI) on the Juno Jupiter polar-orbiting, atmosphere-skimming, mission to Jupiter will coordinate with the several other space physics instruments on the Juno spacecraft to characterize and understand the space environment of Jupiter’s polar regions, and specifically to understand the generation of Jupiter’s powerful aurora. JEDI comprises 3 nearly-identical instruments and measures at minimum the energy, angle, and ion composition distributions of ions with energies from H:20 keV and O: 50 keV to >1 MeV, and the energy and angle distribution of electrons from <40 to >500 keV. Each JEDI instrument uses microchannel plates (MCP) and thin foils to measure the times of flight (TOF) of incoming ions and the pulse height associated with the interaction of ions with the foils, and it uses solid state detectors (SSD’s) to measure the total energy (
E
) of both the ions and the electrons. The MCP anodes and the SSD arrays are configured to determine the directions of arrivals of the incoming charged particles. The instruments also use fast triple coincidence and optimum shielding to suppress penetrating background radiation and incoming UV foreground. Here we describe the science objectives of JEDI, the science and measurement requirements, the challenges that the JEDI team had in meeting these requirements, the design and operation of the JEDI instruments, their calibrated performances, the JEDI inflight and ground operations, and the initial measurements of the JEDI instruments in interplanetary space following the Juno launch on 5 August 2011. Juno will begin its prime science operations, comprising 32 orbits with dimensions 1.1×40 RJ, in mid-2016.
