sPHENIX HCal discussion

["Huang, Jin" <jhuang AT bnl.gov>]

Hello everyone

Please find a draft poster for " Design and test-beam performance of the 
sPHENIX calorimeter system " as on the following link:
https://www.phenix.bnl.gov/phenix/WWW/publish/jinhuang/Meetings/2017.02.06%20QM/sPhenix_QM17poster_calo.pdf
 

Comments and suggestions the next three days will be appreciated. I will 
continuing refining the poster in meanwhile and printout later in the coming 
week. 

Cheers,

Jin
