sPHENIX tracking discussion

["Bertaux, Joseph Tyler" <jbertau AT purdue.edu>]

Thank you for the reply,

I think this is what I was looking for. What I wanted to do is simulate some number of particles and have the output .root file contain branches with both the physical location of the hit and the ID of the chip/strip/ladder. I suspect PHG4InttDetector::AddGeometryNode() might do this for me.

Hello Joseph,

The machinery to do this already exists. The code is in the coresoftware repository:

    offline/packages/intt/CylinderGeomIntt

The code that fills in the details of the geometry class is in the detector construction class that builds the detector model:

   simulation/g4simulation/g4intt/PHG4InttDetector::AddGeometryNode()

It would help if I knew what you are trying to do. Let me know if you want to chat.

Hello all,

Sorry for the bulk email but I wanted to check; is there an existing or decided convention to map between chip/ladder ID to physical x, y, z coordinates where the hit occurred?

I wanted to approach this problem by writing a Fun4All code; is there a way to configure the output so that the hit location and ID are output commensurately for a particular detector?

Thank you,

Joseph
