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.
