RUN 2B L1CAL MEETING MINUTES 22 August, 2002 Hal Evans Report from the Temple Review --------- o See Hal's slides linked off of the agenda for details All Status Reports --- o Nevis - A first layout of the input portion of the TAB has been done . assuming 3 input cables from each ADF - transmission ADF-to-TAB (comments from Denis) . ideas on how to do splitting of signals on backplane . jitter: found new chip <100ps . space: use TABs in every other slot liberates space for chips . power: found lower power chip . Denis will send mail to Nevis with the details - Next task will be to build some test-boards to check that signal transmission using the proposed cables and the Channel Link transmitters/receivers works correctly o Saclay - received splitter pcb's & components - freezing FPGA pinouts for ADF boards - after this . inteface for download . then schematic - another engineer designing SCL fanout card . going well - 1 crate ordered . delivered in Sep/Oct - FPGA demonstrators ordered . arrive in a few weeks - no progress on ADF-to-TAB cables - will need to get Bit3 and VME vertical-interconnect soon . necessary for design of custom backplane . mid-Oct o Monte Carlo - 4e32 @ 396ns generation w/ new SMT geometry . WH --> munu bb + 12-15 minbias . probably will not have more than this - need to check that L1Cal is insensitive to no. minbias . check 1-jet rates for 0.5, 5(?), 7.5, 10 minbias . Jovan will do this at Nevis
