sPHENIX HCal discussion

[Stefan Bathe <bathe AT bnl.gov>]

Hi John, All,

Thanks for the info!
Oops, really?  When I last discussed this with Chris P. on Tuesday, the plan 
was to propose to Brian to move only the shielding blocks that don’t have 
utility lines running on top.  So I didn’t anticipate this.  Maybe Chris 
could send an explanation to the list why the power loss might be an 
implication of this?  (Sorry, Chris, I had to miss yesterday’s planning 
meeting due to end-of-semester business.)  If that’s really the case, this 
work would really have to be well coordinated in order not to impact us too 
much.

Regards,
Stefan
