sPHENIX HCal discussion

[John Haggerty <haggerty AT bnl.gov>]

Hello,

Sorry I missed last week's meeting (my flight was canceled coming back 
from the family to-do).

Since I got back, I finished up some reproducibility tests I was doing 
before I left, and I was able to start trying to radiation damage our 
tiles as suggested in the CD-1 review.  I was able to do it 
parasitically with Takao and and John K.'s TPC electronic test.

I put some slides about it under "First Radiation Dose, July 23, 2018" 
on the previous agenda page:

> https://indico.bnl.gov/event/4836/

I post these here now because I have another chance to expose the tiles 
tomorrow, and if anyone has any suggestions or insights about what to 
dose them to, I thought I'd give you the opportunity to weigh in, since 
it's a one-directional experiment.

I would probably go for another 10 or 15 krad left to my own devices.
