RUN 2B L1CAL MEETING MINUTES
                   19 April, 2005

Present 
o Fermilab      G.Ginther, S.Lammers, M.Mulhearn, G.Pawloski, N.Varelas
o MSU           M.Abolins, C.Brock, D.Edmunds, P.Laurens
o Nevis         H.Evans, C.Johnson
o Northeastern  E.Barberis, D.Wood



Nevis: TAB/GAB (H.Evans)
--------------

o Continuing studies of new EM algorithm
  - no problems found so far
  - will implement in firmware after checking eff vs background for an
    example channel

o Testing trigger term creation firmware in GAB



MSU: ADF v2 (D.Edmunds)
-----------

o Production card testing
  - ~75 cards tested now
  - no serious problems found - only simple repairs
  - should be done by the end of the month

o System test crate - ADF card in all slots
  - power supply noise tests, currents, VME accesses, clock & SCL
    distribution, channel link output, ADC noise levels
  - all looks fine

o Software
  - porting control software to linux
    . will be ready soon


BLS-to-ADF Transition System (N.Varelas, M.Mulhearn)
----------------------------

o Paddle Card Design
  - mechanical design done
  - layout not yet done - working on connection to ADF-to-TAB cables
  - issue is that P0 connector on Wiener crate does not connect easily
    to LVDS cables used
    . paddle card will solve this
  - note: have checked that the pinout is correct - no need to remap
    signals on Paddle Card
  - details of this to be worked out in a meeting tomorrow

o Patch Panels are ready to go out
  - priority to get this out has been lowered while dealing with
    Paddle Cards



Test System (M.Mulhearn)
-----------

o ADF-to-TAB tests
  - successfully transfered data from ADF to TAB last week (4/11)
    . same (constant) event transfered ==> event synch not yet checked
    . previous problem was that cable was plugged in backwards at ADF
  - will continue these tests in more depth after TAB-to-L3

o TAB-to-L3 tests
  - Readout Crate (VRB-VRBC-SBC) tests (4/14)
    . test data in VRB successfully transmitted to SBC using D0
      L2Accepts
      > with spreadsheet control software from Dave Buchholtz
    . but system tends to hang after ~10 minutes
      > lower priority than other issues right now
  - TAB data output verification
    . checked data output from TAB using SignalTap firmware monitor
      > looks fine after firmware bug fix
  - G-Link optical launch power measurements (4/15 & 4/18)
    . measured peak-to-peak of output signal appears to be better than
      "max" in Stratos spec
      > no data transfered: -0.9 dBm
      > data transfered:    -4 dBm
      > after splitter:     -8 dBm (in the ballpark of where we expect)
    . need to make measurements on all boards though
  - Have not yet succeeded in transfering data from TAB to SBC
    . see VRB errors: G-Link synch and fifo-not-empty


Simulation (E.Barberis)
----------

o Working on GAB output in tsim_l1cal2b

o TAB can now run all three algorithms simultaneously

o Will implement the new EM algorithm in the Trigger Rate Tool and in
  tsim 

o Roger working on l2cal_worker

o Trigger studies
  - mu + jets: Ela
  - Higgs: Sabine


Preparing for Test Data (H.Evans)
-----------------------

o see slides linked off agenda for details
