| 3 | *Updates |
||
| 4 | 2 | Alexandre Camsonne | **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 ). |
| 5 | Power section for FPGA |
||
| 6 | Feast : DC DC converter option but might only plan for later depending availability |
||
| 7 | Estimate design completion by September 1 |
||
| 8 | Could get VMM3 in 4 months |
||
| 9 | Bandwidth output from VMM to FPGA : 160 MHz dual edge 320 MBit - if can send all data to FPGA no need to use neighboring |
||
| 10 | |||
| 11 | Cost estimate to see if we can do two runs : |
||
| 12 | |||
| 13 | Transceiver : 100 $ 11 gigE |
||
| 14 | |||
| 15 | Components : |
||
| 16 | |||
| 17 | Timing resolution : 160 MHz timing resolution from clock, 6 ns timing output |
||
| 18 | |||

| 20 | 1 | Alexandre Camsonne | |
| 21 | *Discussion Compton asymmetry |
||
| 22 | 3 | Alexandre Camsonne | |
| 23 | *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 |
||
| 24 | |||
| 25 | Steve including the charge scalers and regular scalers. |
||
| 26 | |||
| 27 | *NIM input : maybe 100 to 200 $ |
