I'm working on a theoretical analysis of a thin 232U UO3 aerogel layer (5-20nm feature size, granular, crystalline, ~98% porosity) in a vacuum in GEANT4, with the desired goal of losing most of the 220Rn (and thus the hard gamma from 208Tl and the residual 208Pb mass). GEANT4 handles the...

Dear experts , when I run the ICRP145_Human Phantoms example following the instructions in the user manual, I get this error response [ VirtualBox:~/Geant4/share/Geant4/examples/advanced/ICRP145_HumanPhantoms/build$./ICRP145phantoms ./Internal -i 9500 -m example.in -o example.out Usage...

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...

Dear experts.Which example file in Geant4 can I use to find the particles and energies produced in the target?

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.

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...

Hi all. I'm a fresh starter on Geant4 and looking for anybody who is also familiar with it. Does anybody have experience with Geant4 ?

I have created a macro file that should produce a Gaussian (Normal) distribution of gamma particles ranging in energy from 0 to 250 keV as follows: /control/verbose 0 /run/verbose 0 /tracking/verbose 0 /gps/particle gamma /gps/ene/type Gauss /gps/ene/min 0 keV /gps/ene/max 250 keV /run/beamOn...

What is the difference between Geant4 and Pythia?

Hi, I have installed Geant4.8.3 and i was prompted that i have installed it successfully i installed according to the instructions here (http://geant4.slac.stanford.edu/tutorial/installation/Geant4.8.3/Linux/Geant4_8_3_Linux_Installation.htm ) i am trying to check my installation by...

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.

Hi, I am new on using the program Geant4. I got it installed into my window xp computer from the instruction from http://geant4.slac.stanford.edu/installation/ I am currently looking for some tutorials on how to use the program. I found some helps from http://geant4.in2p3.fr/2007/prog/prog.htm...

hi, I am a PhD student and I'm looking for a course or resources on the hadronic jets and the models used to deal with them in the code simulation GEANT4. (Example: Bertini model, cascade ...) I will be very greatfull if you can help me. Thank you in advance Sameh

Anyone knows abt Geant4?
