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

He 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 ...

Multiple Coulomb Scattering in Thin Silicon

, 2014
We present a measurement of multiple Coulomb scattering of 1 to 6 GeV/c electrons in thin (50-140 um) silicon targets. The data were obtained with the EUDET telescope Aconite at DESY and are compared to parametrisations as used in the Geant4 software ...

GEANT4 Simulations of Gamma-Ray Emission from Accelerated Particles in Solar Flares

, 2010
Gamma-ray spectroscopy provides diagnostics of particle acceleration in solar flares, but care must be taken when interpreting the spectra due to effects of the angular distribution of the accelerated particles (such as relativistic beaming) and Compton ...

Celeritas: Accelerating Geant4 with GPUs

EPJ Web of Conferences
Celeritas [1] is a new Monte Carlo (MC) detector simulation code designed for computationally intensive applications (specifically, High Lumi- nosity Large Hadron Collider (HL-LHC) simulation) on high-performance heterogeneous architectures. In the past two years Celeritas has advanced from prototyping a GPU-based single physics model in infinite ...

Simulation of Near Horizontal Muons and Muon Bundles for the HAWC Observatory with CORSIKA

, 2017
The HAWC (High Altitude Water Cerenkov) gamma ray observatory observes muons with nearly-horizontal trajectories corresponding to zenith angles greater than $80^{0}$. HAWC is located at an altitude of 4100 meters a.s.l. (70 deg. atmospheric depth of 2400

Research in Geant4 electromagnetic physics design, and its effects on computational performance and quality assurance

, 2009
The Geant4 toolkit offers a rich variety of electromagnetic physics models; so far the evaluation of this Geant4 domain has been mostly focused on its physics functionality, while the features of its design and their impact on simulation accuracy ...

The exact tree-level calculation of the dark photon production in high-energy electron scattering at the CERN SPS

, 2017
Dark photon ($A'$) that couples to the standard model fermions via the kinetic mixing with photons and serves as a mediator of dark matter production could be observed in the high-energy electron scattering $e^- + Z ~\rightarrow e^- + Z + A'$ off nuclei ...
