sPHENIX HCal discussion

["Pontieri, Chris" <cpontieri AT bnl.gov>]

Hello
The original conversation that I had with Brian Streckenbach was about moving 
interior shielding blocks behind hi-bay door 15.  The reason behind this was 
to open up more square footage for storage of the outer hcal sectors.  
It appears now that CA-D is open to removing much more shielding than 
originally discussed, which I agree is a good thing, but will require quite a 
bit more planning.  I will reach out to Brian on Monday and we can start to 
formulate a plan moving forward.  The best case scenario would be zero 
disruption of electrical power so the HCAL group can continue with testing 
the sector electronics.  I will keep all parties involved well informed of 
the plan we develop moving forward. 

If anyone has any specific concerns, feel free to email me directly and I can 
see to it that we address them appropriately.

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
