We met last on Friday, Jan 15. Here's a very brief summary:
1. Tim showed slides which continued our discussion of ABCD vs APV25.
See his webpage:

on+eXperiment+%28MaDPhoX%29
We don't yet have a good understanding of just what must be
built/bought, and what costs will be,
for either of these options, and should work toward that end.

2. Gunter discussed his vision of our data acquisition system. His
slides are attached above.
Again, we need more particulars on how the system would look for our two
readout chip options.
At Jlab, we met a local DAQ expert, Sergey Boyarinov, who is ready to
think with us about what part of the DAQ they can provide, and what we
provide. It looks like they can contribute significantly, but we need to
start talking to each other. In particular, we need to refine estimates
of trigger rate and occupancy to understand how much data we need to
store.

3. John asked for top of the head estimates of effort required to put
together the si system.
We guessed 1/2-1 FTE for each of mech engineer, tech, physicist, and
software. We should be thinking of what it takes to put a system
together in one year.

4. Criteria for selection of readout chip:
Cost
Resolution
Radiation hardness headroom
Can we readout in 25ns?
Support available from the experts?
Can we thin sensors?
