Study on the factors influencing the output response of LYSO:Ce electron radiation detector

open access: yesHe jishu
BackgroundThe total dose effect of ionization on satellites in Geostationary Earth Orbit (GEO) is caused by space particle radiation in GEO.PurposeThis study aims to combine high-performance cerium-doped yttrium-lutetium silicate (LYSO:Ce) crystals with ...

Establishment and validation of a FLUKA radiation model for a medical electron linear accelerator room based on a virtual source

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Purpose In Monte Carlo (MC) simulations of medical electron linear accelerator (linac) rooms using FLUKA, time‐consuming modeling and simulation of the accelerator head are typically required, and FLUKA cannot directly read the phase space files (PSF) for accelerator heads provided by the IAEA.

Simulations of pion production in the Daedalus targets [PDF]

open access: yes, 2012
DAEDALUS, the Decay At-rest Experiment for DCP at a Laboratory for Underground Science will look for evidence of CP-violation in the neutrino sector, an ingredient in theories that seek to explain the matter/antimatter asymmetry in our universe.

Cell survival comparison of proton, helium, and carbon ion interlaced minibeams in water phantom simulations

open access: yesMedical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Radiotherapy is a key in cancer treatment, with particle therapy providing better tumor targeting and sparing healthy tissues. Particle Minibeam Radiotherapy (PMBT) integrates the advantages of spatial fractionation into particle radiotherapy by employing submillimeter‐sized beams, thus improving the therapeutic ratio by reducing ...

Predicting Nitrogen Isotope Fractionation in Nitrate Deposition on Early Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Noachian and early Hesperian Mars were likely warm and wet, with an atmosphere abundant in molecular nitrogen. The recent discovery of nitrate deposits in the Yellowknife Bay mudstones at Gale Crater confirm the existence of nitrogen oxides (NOX) on Noachian Mars. The processes responsible for the production of these nitrates would fractionate

Martian Proton Albedo as Signature of Near‐Surface Water

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Investigation of The Gamma Ray Shielding Behaviour of (90-x)TeO2—xMoO3—10ZnO Glass System Using Geant4 Simulation Code and WinXCOM Database

open access: yesCumhuriyet Science Journal, 2019
In this study, mass attenuationcoefficients (µm), transmission fractions (T), mean free path (MFP) and halfvalue layer (HVL) of the (90-x)TeO2—xMoO3—10ZnOglass system (x=10, 20 and 30 mol%) were calculated at the gamma rayphoton energies of 356 keV, 662 ...

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.
