Detector Geometry Simulation Using GEANT4

Journal of Nuclear Physics, Material Sciences, Radiation and Applications, 2015
Neutrino oscillation is an important phenomenon to explain the massive nature of neutrinos. this quantum mechanical phenomenon can be understood as mixing in quark sector just like the one we have in lepton sector. Observed deficit of solar neutrino flux is explained through neutrino oscillations and this study is the only way to investigate for small ...

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, EarlyView.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

FullSimLight: ATLAS standalone Geant4 simulation

, 2019
HEP experiments simulate the detector response by accessing all needed data and services within their own software frameworks. However, decoupling the simulation process from the experiment infrastructure can be useful for a number of tasks, amongst them the debugging of new features, or the validation of multithreaded vs sequential simulation code and

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 ...
