RUN 2B L1CAL MEETING MINUTES 24 February, 2005 Present o Fermilab G.Ginther, S.Lammers, G.Pawloski, M.Mulhearn, V.O'Dell, S.Rapisarda, R.Unalan, N.Varelas o MSU M.Abolins, J.Biehl, C.Brock, D.Edmunds, P.Laurens o Nevis H.Evans o Northeastern E.Barberis, D.Wood o York W.Taylor Nevis: TAB/GAB (H.Evans) -------------- o Testing new EM algorithm firmware wrt simulation - problem in implementation found ==> multiple local maxima for 2TT ROIs . still working on solution o Beginning to test first version of Trigger Terms creation firmware in the GAB o Settling on Vicor system as TAB/GAB crate power supply - getting quotes now - but delivery time likely to be rather long - will need to continue to use temporary bench supply at Fermilab o Sending big shipment of hardware to Fermilab later today - 1 TAB/GAB crate - 1 TAB (will now have 2 at Fermilab) - 1 GAB - 5 TAB-to-GAB cables - 3 VME/SCL-to-TAB/GAB cables - ~260 ADF-to-TAB cables MSU: ADF v2 (C.Brock, D.Edmunds) ----------- o Problem w/ gold-plating PCBs (at board manufacturer) - should receive first partial shipment (from Adco) at MSU next week - full production around March 8 - approx. 1 week delay from last prediction o Now using final Wiener crate for ADF testing at MSU - looks ok o Now have tested last 4 ADF v2 pre-production cards - treating in same way as production cards when they come in - now running crate w/ 10 cards installed o BLS-to-ADF prototype system at MSU - will connect this to ADF at MSU to see that signals arrive correctly Test System ----------- o Meeting last week with Marvin and Dean to discuss ways to make cabling BLS-to-ADF system easier - proposing to extend the Paddle Card (plugs into back of ADF crate) This will allow easier access to connectors and more room to plug them in. - layout being done now at Fermilab - Dan claims that this would be a very dangerous thing to do o ADFs will arrive at Fermilab in two weeks (w/ Dan & Philippe) - also communications crate and SCLD Simulation (W.Taylor) ---------- o Note describing studies of new EM algorithm is available for group comment. Please send suggestions/questions to Sabine and Greg. - http://www-clued0.fnal.gov/~pawloski/L1CalIIbSim.pdf o Still working on interface b/w L1Cal and Cal-Track - crashing deep in the framework: need help from experts on this o Unpacking - Philippe has an example of how to do this outside of IOgen framework. Forms the basis of what Todd has done. . used in ScriptRunner and L3 and to extract Trigger Terms from the Framework - Note: IOgen is required for use in the simulator Announcements ------------- o Trigger Simulation Meeting: Thurs 10:30 - 12:00 o Integration Meeting during Collaboration week: Thurs 2:30 - 4:00
