sPHENIX discussion of software

Dear HCal group

 

I am writing to bring to your attention a major change in the HCal simulation was merged this morning. A technical note is part of the pull request below:

https://github.com/sPHENIX-Collaboration/coresoftware/pull/1679

which including magnetic field in HCal absorber, flip of the HCal to sPHENIX coordinate system, and fixing HCal envelopes

 

A few TODOs and cautions:  

• Please update your local macros if you use custom HCal macro, as the envelope and field map have changed in the HCals.
• There were overlaps in both inner and outer HCal (beyond the G4 overlap check scope). For any study involving the HCals, it would worth redoing with these fixes now in build
• We need a new phi-0 calibration for the first sectors for both HCals, which currently has a small shift [link to HCal in] [link to HCal out]
• We need to implement the new HCal support ring that holding outer HCal up, which is in the acceptance of outer towers.

 

Let me know any question or suggestion too.

 

Cheers

 

Jin
