Geant4 simulation of sFLASH experiment [PDF]

Proceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017
The goal of Super Fluorescence Air SHower (sFLASH) is to reduce the current fluo-rescence yield systematic uncertainty to improve energy measurement of ultra-high en-ergy cosmic rays. The experiment was performed at SLAC National Accelerator Labora-tory to measure the air fluorescence yield from extensive air showers.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

GEANT4 Montecarlo simulations: a multithread approach [PDF]

Proceedings of The Golden Age of Cataclysmic Variables and Related Objects IV — PoS(GOLDEN 2017), 2018
In this paper we will show the hardware and software implementation of the gforcr computing cluster operating in the LCD laboratory at the IAPS / INAF headquarters in Rome. The comput- ing system is used to perform Monte Carlo simulations using the GEANT4 toolkit in multithread mode. The simulations are designed to evaluate and reduce the background of

Generalizability of deep learning–based dose conversion model in proton beam therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background In proton beam therapy (PBT), the analytical pencil beam (PB) algorithm involves dose uncertainties in inhomogeneous regions, making accurate Monte Carlo (MC) dose calculation desirable but time‐consuming. Deep learning, converting the dose calculated by the PB algorithm into an MC‐equivalent dose distribution, can resolve the trade‐

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
