What is geant4: Definition and 14 Discussions

Geant4 (for GEometry ANd Tracking) is a platform for "the simulation of the passage of particles through matter" using Monte Carlo methods. It is the successor of the GEANT series of software toolkits developed by The Geant4 Collaboration, and the first to use object oriented programming (in C++). Its development, maintenance and user support are taken care by the international Geant4 Collaboration. Application areas include high energy physics and nuclear experiments, medical, accelerator and space physics studies. The software is used by a number of research projects around the world.
The Geant4 software and source code is freely available from the project web site; until version 8.1 (released June 28, 2006), no specific software license for its use existed; Geant4 is now provided under the Geant4 Software License.

    Product Cross Section For Zn66 in Geant4

    Dear experts, I want to calculate the cross section (Product Crosssection) of the Ga66 element produced by sending deuteron to the Zn 66 element, which is my target in Geant 4.Is there a Geant4 sample file where I can do this calculation, so in which sample file can I calculate it? Do I need to...

    A Exploring Secondary Particle Generation from X-Ray Collisions in Geant4

    Hello, I need some articles and pictures about secondary particle generation when x-ray(with different energy) collides with silicon and aluminium materials. I am simulating this phenomenon in geant4. I just want to validate my result.

    Alternative software to geant4?

    I need to simulate a gaseous detector involving UV Lamp's. I have tried using Geant4. Now i think this says by itself, two geant4's weak point: Gaseous medium, it is relatively bad at simulate in it, and low energy gamma gun, near 30 eV, which is too low for Geant4's physicslists. Garfield was...

    Comparing Results of MCNP vs Geant4 for Shielding Design

    I'm curious if anyone has any opinions in the results from MCNP vs Geant4 for shielding design. I like that Geant4 uses a more modern syntax, but iv'e also heard that MCNP gives better results.
