1. DAQ May 25, 2000 Harry Nelson

2. Meeting Schedule March - meeting at SUF, laid plans for overall work plan 1/week at UCSB Re-started weekly phone meetings - yesterday Late June DAQ meeting in UCSB - a postdoc candidate is planned to attend

3. DAQ `Bandwidth’ At CDMS-II, near to saturating Fast Ethernet from in-crate processor to the event builder In-crate processors are somewhat behind the the competive `box’ processors (Bauer) - `quiet’ VME (eliminate VXI) (Holmgren) - VME > Bit3 > PCI

4. `Bandwidth’ cont’d PCI Box > Event Builder with Myrinet, instead of Fast Ethernet - looks appealing –non-DAQ - >100 Mbyte/s –cost ? About $20K more Could even stay Mac + Labview In Crate Decimation - no progress, and it is another route to `Bandwidth’ solution

5. Crate 2 Some more infrastructure - probably Craig Maloney > SUF to work over phone with Don Holmgren in next month Would like to implement In-Crate Decimation, or filtering

6. Functional Blocks ZIPS - Digitizers - a substantial set in hand Time History Unit –Veto - use `old’ digitizers, and make into an `analog’ time history unit this will be the prototype DAQ environment at UCSB (Craig Maloney), to in part, transfer know- how about device drivers from Don Holmgren –Detectors - sparse occupancy in Soudan various proposals, one written up by Craig Maloney

7. Functional Blocks Veto - peak sensor (Ray Bunker) - prototype Veto - pulser (Ray Bunker, Tony Piro) - prototype Veto - HV power - investigating CAEN record (Ray Bunker)

8. Functional Blocks ZIPS - RTF/ `Trigger Conditioner ‘ (Burke, Sander) –Left debugged/fixed/layout fixed –Right now back from prototype, being tested ZIPS - VME/ `Trigger Logic Board’ (Burke, Sander) –Issues about handling of trigger lines

9. Soudan LAN Two T1’s - 100’s of Kilobytes –not enough for us and Minos! –What to do? Mass storage at Soudan –Tevatron Run-II/CLEO-III …. AIT-2 (Sony) 25 Gbyte/cassette Exabyte `Mammoth-2’ similar

10. Must do’s UCSB Postdoc Settle Trigger Logic Board Settle High Voltage for Veto Make a `new-style’ DAQ this summer for veto
