Hello, I’m a physicist and I’m currently in a medical physics residency program. I’m developping a project in which we try to calculate secondary neutron dose in and out-of-field of treatment produced by a Varian iX 15MV beam. But for that, right now, I need the phase space files of this specific beam. I know there is a series of phase space files in IAEA website (here: Index of /phsp/photon1), but there isn’t specifically this one of the 15MV beam. Can anyone help? Possibly someone has this phase space file or can recommend a place where I can find it? I’m aware of Varian Virtual LINAC wep app, but I’ve been informed that this is no longer available. So I’m in search of other options. Thank you in advance! Any information will be valuable since I’m new to both Geant4 and this project.
Geant4 Version: 11.2.1
Operating System: Windows 10
Compiler/Version: IDE Visual Studio 2022 17.9.7
CMake Version: 3.29.3
Hi Emily Oliveira Costa If you already have the 15 MV phase space file available, I would appreciate it if you could share it with me. Please find my email address below.
Phasespace files for commercial LINACs are not typically released to the public. Its unlikely you will be able to find the one you need floating around on the Internet or that anyone would break their agreement with Varian to give you one. If your hospital/clinic has an agreement with Varian you might be able to get the files from them, they certainly would have the files already created.
A bit of a warning, the IAEAphsp interface for Geant4 is very old at this point and you will not be able to use it out of the box for version 11.
EDIT: Just realised that the OP is 1.5 years old and was necro’d.
Sorry for coming back to you 1.5 years afterwards - somehow I did not get this message notified. As this thread was ‘revived’ anyhow, we let you know that we made available, from version 11.4, an new advanced example on the use of IAEAphsp files, with the IAEAphsp classes adapted for MT runs and tested with the pshp files available at the IAEAphsp website. This is an update on the work published in 2012 at the IJRB Journal [https://doi.org/10.3109/09553002.2011.627977]
