sPHENIX discussion of software

["Frawley, Anthony" <afrawley AT fsu.edu>]

Hi All,

I updated my slides with the outer radius error on slide 3 fixed.

Cheers

Tony

Chris - new inner Hcal

 

Page 3:

Jin & Achim: any support structure?

Chris: we can add later when designed.

 

Jin: Tilt angle can be configured here?

Chris: Yes. Tilt angle configurable with a geometry check

 

Page 4:

Chris, angle scan plot has unit of degrees.

 

Page 5:

John: we probably going to use 24 segments for inner Hcal cross the polar accepance

 

Summary:

Ed: why total radiation length changed?

Chris: Not quite understood yet.

 

Jin: do we expect large change in the outer Hcal

Chris: air gap and angle in outer HCal should be close between current GitHub version and the coming version.

 

Tony - Tracker update

 

Page 2:

Jin: What was the change in X0?

Tony: S1 reduced from  2.3%  to 1.2% X0, which allow us to reduce the max radius

 

Page 3:

Tony: correction, outer radius in this slides should be labelled 60cm.

 

Summary:

Tony: we still connects a few strips together to readout in one readout channel, but have not yet quantified in Geant4

 

Tony: going to ladder geometry would usually leads to a few percent worse in resolution.

 

Chris: field map from current + sPHENIX field return, should represents the best estimation of the sPHENIX field at the moment.

Dear All,

 

This is reminder of our weekly sPHENIX simulation meeting Tue July 14 1-3PM. For residents at BNL, we will meet in the 2-160 conference room as usual.

 

Currently on the agenda are HCal simulation update by Chris and Tracking studies from Tony. More topics are welcomed too.

 

The agenda page is at https://indico.bnl.gov/conferenceDisplay.py?confId=1182   , for which the modification password is 1008
