sPHENIX EMCal discussion

["Ilardo, Matthew" <milardo AT bnl.gov>]

I have all the parts processed, what surfaces are most important? Would you like to come here around 2 to go over the report you would like?

Hi Matt,    I know you said processing the survey results was very labor intensive, but as you can read below, we are at a critical point in our assembly process. If you are not able to provide the survey results by this afternoon, please let us know asap. We need to move forward !  Thank you !  Mike

PS   Does processing this type of survey usually take this long (2 weeks) ?   We would need to know this for future requests !

Dear Sean,

 

I agree it looks great (and thanks for all the pictures).  Do you know when you will hear back about the survey?  Is it possible you’ll hear before the target to make a decision on the gluing tomorrow afternoon as we discussed in the EMCal meeting on Friday?

 

Best,

Anne

All,

 We did a dryfit of Sector 0 with 96 blocks this afternoon.

(A few of the blocks had wet optical couplant, so we used some spares
for the photo.)

I think all looks good. We are still waiting on the survey numbers for
the sawteeth. So maybe we want to hold off on epoxying things in place
until we see those, but we didn't see any obvious problems with the
fitting that would indicate significant dimensional issues.

"Good work" to all who contributed to the effort.

Sean
