RUN 2B L1CAL MEETING MINUTES
                   3 May, 2005

Present 
o Fermilab      T.Adams, L.Bagby, D.Edmunds, G.Ginther, M.Mulhearn, 
                Md.Maimuddin, G.Pawloski, P.Renkel, A.Stone, D.Wood, 
		N.Varelas, H.Weerts
o MSU           M.Abolins, C.Brock, P.Laurens
o Nevis         H.Evans
o Northeastern  D.Wood



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

o Continuing studies of new EM algorithm
  - simulating various versions

o Testing trigger term creation firmware in GAB

o Power supply arrived from Vicor
  - shipped to Fermilab for testing in Test System
  - will buy more of these as soon as the 1st checks out

o Will start safety review process

o Ship more TABs to Fermilab
  - will check to see if there is any reason to keep a substantial
    number at Nevis



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

o Production card testing
  - all 100 have been tested
  - only three have minor problems (LEDs, etc)

o Fully populated crate testing
  - this is now shifting into high gear (20 ADFs per crate)
  - using final version of firmware
  - this is far enough along that we could think of bringing crates of
    ADFs to Fermilab
    . need to have a place to store these

o Oversampled ADF data
  - can capture more of these signals now, using an automated
    acquisiton
    . available next week
    . will also have the data sent to the TAB available
    . sampled over an entire turn
  - this will be useful for e.g. verifying timing of BLS signals


BLS-to-ADF Transition System (A.Stone)
----------------------------

o Paddle Card Design
  - design is almost finished
  - rechecking the ADF-to-TAB connections to make sure that everything
    is correct
    . need to verify TAB connections at backplane
    . will circulate this when ready
  - will probably try to order one crate's worth next week
    . if everything goes well

o Patch Panels final design done
  - will order a few more "pre-production" modules to make sure that
    it's right



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

o ADF-to-TAB, TAB-to-L2(fic), TAB-to-L3, TAB-to-GAB
  - all checked using same data on every event
  - error checking is being done at the FIC level
    . seeing rather frequent protocol errors, but have just started
      these tests

o To Do
  - real event synchronization (i.e. seeing the correct event
    synchronized across the system)
  - data to tape in a short test run
  - should be able to reach May 15 milestone of vertical slice


Pulser (B.Kehoe)
------

o see slides linked off the agenda page
  - some of the discussion is reproduced below

o Use of Pulser for timing studies
  - pulser signals are fairly similar to real data
  - timing can be adjusted

o Structure of Pulser code
  - based on L1Cal examine code
  - can run "online" as an examine, but normally used offline for
    reading files from disk/SAM

o Pulser injects charge at preamp level
  - can check for (historically) most probable problems - BLS system
