Re: Question Use of Phase Space File on ML2 (Galileo Munoz)
Date: 16 Feb, 2011
From: Claudio Andenna <Claudio Andenna>

*)How can use the Phase Space File in Medical Linac2 (ML2) geant4 example for reduce the computation time?

You should create your own phase space files setting /primaryParticleData/sourceTypeName randomTarget Once you have your files you should set /primaryParticleData/sourceTypeName phaseSpace And /primaryParticleData/calculatedPhaseSpaceFileIN your_Phase_Space_File_Name

*)Under what parameters is currently accepting the ML2 example? The ML2 example is just an example. The accelerator is not a true one and the user should create the accelerator of his interest.

*)Do you know how much data should be collected to obtain a good simulation? Under what parameters? Generally we use some billions of primary electrons to simulate the dose in a water phantom. The parameters should be set according your necessities and possibilities for example the voxels sizes drive the convergence and the precision.

*)There is a file in which I believe we can introduce experimental real data (VoxelsTest.txt) for comparison with simulated data.. Right?? How can I do that? You are right, you should substitute the data in the file with yours.
