Dear all,
Happy New Year to you all and Best Wishes for 2016.

Sorry I would not be able to attend the meeting.
Here is a brief report on the GEMs

1-) The second chamber: was built and is under tested and looks good 
We had a large amount of cosmics data over the Xmas break (no x-ray data 
because of the break).
I will send some plot later

- We are bringing the chamber to JLab on the week of Monday 18th 
January. Eugene has some space reserved in EEL for it
ad Xinzhan will be the in charge of setting it up onece it is there

2-) We still have to reopen and glue together the frames of the first 
chamber. (replacing the screws and o-ring)
This is on schedule for end January - early February

3-) Electronic from CERN:
- The additional FEC and the second crate are reserved and available for 
us at CERN and I will have them chip to UVa as soosn as possible
- There are still some glitches (at CERN level about the payment 
process, but I am in talk with the people over there to find a solution) 
but it is mainly a CERN problem
- I am arranging to borrow 2 more FEC/ADCs from colleagues at CERN and 
Florida Tech (in addition to the 6 that we already have and need).
- These additional modules however are not guaranteed to work properly 
(there seems to be some problems with at list one of the card)

-) DAQ: there seems to be some recent progress from Bryan on the 
integration of the electronic into CODA + TI
I guess Krishna or Li are reporting on this.

Best regards
