Hello

Hello,

I just released version 0.2.1 of beamdpr, a tool I use to manipulate phase space (egsphsp1) files. Updates since the last release include

– handling arbitrarily large files

– randomizing the particle order in the file

– sampling and combining phase space files (to get a representative sample of many large files)

– modifying particle weight distribution by linear function of off-axis distance (and preserving total weight of file)

– printing arbitrary fields, eg to print the x and y coordinates of the first 100 particles:

beampdr print my.egsphsp1 –field=x –field=y -n=100

This release can also be installed very easily on your mac via homebrew with:

brew tap henrybaxter/tap

brew install beamdpr

I hope someone finds this tool as useful as I have, and I look forward to any feedback you may have.

I have made a simple tool that supplements beamdp (from BEAMnrc) by allowing arbitrary translation, rotation, reflection, and combination of phase space (egsphsp) files. It is also a starting point for more tools, which I will work on as I need them. If you’re interested in this work, please check it out:

And let me know if you find any problems or have any questions 🙂

I would like to visualize what is happening with my BEAM simulation.

I would like to visualize what is happening with my BEAM simulation. Using beam_gui I can visualize the basic geometry of the linac (‘accelerator preview’). Is there a way to visualize the photon tracks superimposed on the geometry?

I have seen reference to egs_windows, but I believe this has been replaced with egs_view.

It seems egs_view requires an EGS .egsinp, not a BEAM .egsinp, since it gives:

>> EGS_BaseGeometry::createGeometry: no geometry specification in this input

I thought perhaps previewRZ, but probably the same problem since it gives:

>> This input file is not in the morphed format! Exiting.

What is the appropriate tool to use to visualize photon tracks and geometry of a BEAMnrc .egsinp and attendant files?

Thanks!
