sPHENIX MAPS tracker discussion

[Martin Purschke <purschke AT bnl.gov>]

All, (cc'ing the DAQ list b/c of mutual interest/awareness, sorry that 
some of you get this twice)


As we discussed briefly in Thursday's MVTX meeting, I hooked up the 
current MVTX-dedicated GL1/GTM to the FELIX in EBDC11.

Please refer to our Oct 26 discussion about the fiber distribution from 
the GL1/GTMs: https://indico.bnl.gov/event/17586/

To document today's work, I made a derivative document and (rather than 
spamming two lists with MBs of pictures) uploaded it to that same 
meeting in indico:

The TL;DR is:

- the MVTX GTM minipod is hooked up to the FELIX, as is the busy return
- the physical "fibering" is made exactly as we agreed on in October 
with the 2x12 MPO -> 24 LC breakout cassette
- Jo, Joe, Yasser and I can now take it from there. It is unlikely to 
come alive just on the first try. But all hardware is in place.

Have fun, and a good weekend!

        Martin
