2005-04-11 L1 CAL Integration Mtg
Far Side, 13:00

Attendees: Alan Stone, Lyn Bagby, Sabine Lammers, Johnny Green
Md Naimuddin, Peter Renkel


Sabine and Mike will help Lyn with configuring the TAB to get 
output from the transmitter, so a measurement of the optical power 
output can be performed.  Should involve Mikolaj.

Request the documentation for the bit error rate measuements 
performed at Nevis on the TAB/GAB.  We will be using a different
receiver at Fermilab. 

Debriefing meeting for Electrical Operations with the lab division.
supervisor this afternoon.  Lyn will be attending.  The message from
D0 will be that the L1 CAL upgrade effort is heavily dependent on
the electrical support group.  Look into additional crates so a 
sidewalk test stand can persist after the installation of the new
system in the fall.

The optical cables (50 micron, appropriate length) were ordered and
should be here later this week.  We do not have at D0 cables of the
correct wavelength and long enough to run from the test stand to the
MCH 2nd floor.


Report from Johnny Green on Transition System

Got a few mock-up modules for the new transition paddle card.  Put
connectors on two of them.  220 mm deep, 6 u in height.  

The ERNI connector we have been using all this time was the wrong
part for the application we want.  Will get the correct part from 
Harding.  Does not affect the signal or channel mapping.  Mainly
a mechanical issue.

Will need to add a little bump to the front of the board for the 
pair of pleated foil connectors. 

The schematic for the patch panel card has been revised to incorporate
changes suggested by Dan Edmunds, modifications for the cable
clamps, moving the connectors a little, updating silkscreen, etc. 

Make another version (#2) of the patch panel cards - order and stuff 
3 or 4.

Transition test board is on hold, until the final version of the transition
paddle card has been made.  We don't need it right away, but it will
be important for quality control later on.  This became clear from tests
Dan Edmunds performed with the revised BLS only paddle card.


Discussion on why Mike had to flip the signals from the ADF to TAB.
What was the source?  If only test data from the ADF was sent, then
only the LVDS cable connects the ADF to TAB, and nothing from the
transition system would be in play.  Are the cables ok?  Need to
investigate, and soon.


Report from Sabine and Nayeem on Readout

TAB readout.  The COOR resources file is not set up correctly.  
Scott did not differentiate our test readout from global readout.
Fix ourselves, then tell Scott.   Would require reinit of COOR.

Met with Elizabeth and Arnold.  Created a zero bias template.
Clear on what to do in the future.


Alan, Peter and Rahmi will work on a new draft note of the labelling 
scheme this week.
