Celeritas: Accelerating Geant4 with GPUs
EPJ Web of ConferencesCeleritas [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 ...

GEANT4 APPLICATIONS IN SPACE [PDF]
Astroparticle, Particle and Space Physics, Detectors and Medical Physics Applications, 2008 Use of Geant4 is rapidly expanding in space application domain. I try to overview three major application areas of Geant4 in space, which are apparatus simulation for pre-launch design and post-launch analysis, planetary scale simulation for radiation spectra and surface and sub-surface explorations, and micro-dosimetry simulation for single event ...

Nuclear spectroscopy with Geant4 [PDF]
EPJ Web of Conferences, 2016 The simulation toolkit Geant4 was originally developed at CERN for high-energy physics. Over the years it has been established as a swiss army knife not only in particle physics but it has seen an accelerated expansion towards nuclear physics and more recently to medical imaging and y- and ion-therapy to mention but a handful of new applications.

EPJ Web of ConferencesThe analysis category was introduced in Geant4 more than ten years ago (in 2011) with the aim to provide users with a lightweight analysis tool, available as part of the Geant4 installation without the need to link to an external analysis package. It helps capture statistical data in the form of histograms and n-tuples and store these in files in four ...

Influence of backscattered electrons on exit beam of miniature transmission X-ray tube using Geant4
He jishuBackgroundWhen an X-ray tube operates, a large number of backscattered electrons are generated inside the tube. Under the influence of the electric field inside the X-ray tube, these backscattered electrons are pulled back to the anode target by the ...
