[Solid_ec] SoLID EC meeting at 10am

[Yi Qiang]

Hi Xiaochao,

I think it will be good to keep some safety margin, say a factor of 2. 
Actually, in my DAQ design, I left 240 channels (1 FADC for 2 sectors) 
for forward scintillator readout. Also finer segmentation will 
definitely help relax the requirement on PMTs.

Thanks,
Yi

The table will be presented at the beginning as well.  Xiaochao would like to have these slides by Thursday noon, to allow some time for working on the slides.
