RUN 2B L1CAL MEETING MINUTES 14 November, 2002 Present o MSU: P.Laurens o Nevis: H.Evans, J.Mitrevski o Northeastern: D.Wood Discussion of Action Items from Saclay Workshop ----------------------------------------------- 1) 10-bit TT raw E - Questions . 10-bit could provide a history of the crossing around it with finer sampling than BX and also for multiple BXs . are there any other issues than determining filter param's? - Multiple BXs could be provided using 8-bit values from TAB . need to work out how this would work . would not give oversampling - Who can we ask to get more input on this? . Jim L., Bob K., Jet E-scale group... - If use ADF to save 10-bit samples how can we choose specific triggers to do this? a) ADF internal trigger mode: self-triggers on TT over threshold . this is probably easiest way to do it b) special trigger qualifier bit ==> new action item: how long would it take to collect data required to determine filter param's? How many measurements per threshold for a given TT are required? (Denis will need to comment on this) 2) Cabling the System - Dan is at MSU - has not had a chance to look at this specifically . will be at Fermilab next week 3) Parallel Commissioning - Note: no matter what happens in terms of schedule, it will be easiest to build the entire system outside of the MCH - Timescale . whether we need to do this parallel commissioning or not (build more splitters) will depend on how the schedule goes > if things are on time ==> will not be necessary > should talk with D0 management about whether getting another group to build more boards is possible 4) Prototype Integration - Dan is at MSU - will talk with him next week at Fermi 5) Trigger Terms from the GAB - Involvement of other groups than Nevis? . no one has volunteered yet - but we should look for groups . Trigger Board? 6) Cal-Track Match Data - Have not talked with Ken about this yet . he previously expressed interest in doing these studies 7) Next Workshop - send thoughts... - should keep this small and specific enough to really be a workshop . might not want to have an overall trigger workshop
