RUN 2B L1CAL MEETING MINUTES 6 May, 2004 Present o Fermilab M.Adams, T.Adams, J.Mitrevski, S.Rapisarda, W.Taylor, H.Weerts o MSU D.Edmunds, P.Laurens o Nevis H.Evans o Saclay J.Bystricky, D.Calvet, E.Perez Nevis: TAB/GAB (H.Evans) -------------- o TAB/GAB prototype tests - continue work on long term TAB-to-GAB data transmission tests - B.E.R. < 1e-13 (no errors observed so far) - will continue pushing on this - try to generate "pathological" data o L2/L3 readout tests will continue next week - assuming we squeeze in some time between runs Fermilab: TWG (S.Rapisarda) ------------- o Working on spec of 32-channel board - may be able to put this on a double-wide 6U board MSU: ADF (D.Edmunds) -------- o Continuing work on getting design ready for ADF v.2 - have mainly moved to layout phase o Have started writing a document about how ADF cards will be tested - note: will probably need to use a Channel Link test card (Saclay's or Nevis'?) Saclay: ADF (D.Calvet) ----------- o see slides linked off agenda o B.E.R. measurement of Channel Link Tester - Measuring ber at 448 MHz - using Channel Link Test Card - send pseudo-random data or fixed data pattern o Summary (using scope) - eye pattern is nicely open - ber < 1e-15 for all cable pairs - operates correctly w/ and w/out DC balancd and DeSkew o Summary (using data capture on Channel Link Tester) - ber < 3e-14 for one link (no xmit errors) . link run for 40 hours - tests continuing o Further Validation Tests - operate 1 ADF w/ clock from SCLD - operate 2 ADFs w/ clock from SCLD - meas. signal on TAB side ==> influence of TAB termination - determine optimum pre-emphasis level - check data on TAB side during extended test run period . note that this was not completely tested in Oct.03 integration . ADF can send constant, pseudo-random, pre-stored data patterns . TAB can count parity errors . but should really do a bit-by-bit comparison of the data as it arrives - particularly pseudo-random o When to do the data transfer test? - also need to do TAB L2/L3 readout tests o SCLD: layout finished - in final checks - go to production next week or week after - will prod. 2 PCBs, cable one - test at Saclay then send to Fermilab Online Software (P.Laurens) --------------- o Philippe is concentrating mainly on the ADF work Offline Software (T.Adams) ---------------- o Todd has been talking with Philippe about existing code - will use this as a basis to make a new class Simulation (E.Barberis) ---------- o Simulation workshop on May 11 UIC: Cabling (A.Stone) ------------ o see summary linked off agenda page Pre-Installation Responsibilities (H.Evans) --------------------------------- o see tentative list linked off agenda - also note new "Installation" web pages off of main L1Cal page o Please send comments to Hal as soon as possible - we need to have this completely clarified by Fresno
