*VMM : ESD settled, question if we need neighboring strips : yes, though need to make sure the mapping of GEM is correct with VMM mapping ( will check with Nilanga / Kondo ).
Power section for FPGA
Feast : DC DC converter option but might only plan for later depending availability
Estimate design completion by September 1
Could get VMM3 in 4 months
Bandwidth output from VMM to FPGA : 160 MHz dual edge 320 MBit - if can send all data to FPGA no need to use neighboring
Cost estimate to see if we can do two runs :
Transceiver : 100 $ 11 gigE
Timing resolution : 160 MHz timing resolution from clock, 6 ns timing output
*Discussion Compton asymmetry
*Test setup : small issue with loading the firmware - threshold on VTP power supply was a bit too low and when it went above threshold it shutdown and reset the crate
Steve including the charge scalers and regular scalers.
*NIM input : maybe 100 to 200 $
