RUN 2B L1CAL MEETING MINUTES 6 September, 2005 Present o Fermilab L.Bagby, J.Ban, G.Ginther, S.Lammers, M.Mulhearn, Md.Naimuddin, V.O'Dell, N.Varelas, A.Stone + ??? o FSU T.Adams o Indiana H.Evans o MSU C.Brock, D.Edmunds, P.Laurens o Nevis J.Parsons o Northeastern o York W.Taylor (apologies to those I couldn't see) MSU (Edmunds/Laurens) --- o Philippe working on control software - main topic COOR parameter specification . have a starting point w/ Scott for this o 3 A fuses at Fermilab on ADF replaced w/ 2 A (per ORC) Nevis (Parsons) ----- o everyone is at Fermilab now Status from the Test Stand (Mulhearn) -------------------------- o "Passed" ORC for Test Stand . can operate TAB crate unattended . need to change fuses on ADFs and make a few other minor fixes for the rest o Working w/ Nevis engineer (Jaro Ban) at Fermilab - mainly on intermittant problem that sends data from wrong BC to L2/L3 o Understanding algorithm checking software at Fermilab o L2/L3 Data format - "eta swapping" problem observed in unpacker is now understood . numbering convention difference between ADF and TAB . will be adjusted in TAB firmware - change to format to reflect the way data is stored in TAB chips - add 32 0's to TAB L2/L3 data for data alignment in unpacker . not clear if this is really needed - when these changes are made, the documentation needs to be changed Discussion of Shutdown Date --------------------------- o Desirable Items - essentially - reduce physics commissioning time as much as possible by doing work beforehand - More Trigger Towers split off - Hot-Tower Finder - Do a "long weekend" installation by working day and night . need to be *very* sure that everything is ready if we do this - need to make sure students/postdocs don't miss out on physics analysis o Management Issues - need guidance from management/the lab about when the decision will be made - spokes preparing a core physics program for 2006 and beyond . need to see how this impacts the trigger program - ask spokes to come to next Tuesday meeting and explain their vision for the trigger to the group - Oddone will (probably) come to D0 to present his views of the shutdown date . we should make sure to attend
