3. Advanced Neutron Spectrometer Simulation
Mr John Watts (physicist)
27/05/2014, 14:00
A Geant4 simulation of the Advanced Neutron Spectrometer (ANS) will be described. ANS uses a volume of vinyltoluene scintillator with embedded scintillating glass fibers composed of 20% Li2O-15% MgO-64.4%SiO2-0.6%Ce2O3 with the lithium being 95% Li-6. Neutrons would be captured in the glass which has different scintillation characteristics in terms of spectral output and timing from...

The Extreme Universe Space Observatory (EUSO) is a new type of observatory that uses Earth’s atmosphere to detect the Extreme Energy Cosmic Rays (EECRs), those with energies in excess of 1018 eV. Studies of the nature of EECRs provide us with some information about the origin, acceleration and propagation of the primary cosmic rays. Such studies are based on the interpretation of the extensive...

Dr Masanobu Ozaki (JAXA)
27/05/2014, 14:50
ASTRO-H is an international X-ray observatory scheduled to be launched in 2015. To design a low particle and X-ray background structure and estimate the in-orbit background for observations planning, Geant4 acts as the central engine of the Monte Carlo simulation. Here we will present about the cosmic X-ray background shield study and the comparison between Geant4 ver.10 activation and a...

Exposure to space radiation and the associated health risks pose a major challenge to the growth of deep space exploration. The effects of such radiation on electronics and shielding have been studied in considerable detail and have led to novel methods and design strategies for minimizing equipment failure and developing hardening strategies. Similar efforts to better understand the effects...
