DATE-based DAQ Hideyuki Sakamoto CM 22, RAL 19/10/08 1

R 8 cosmic-ray test stand • In R 8, cosmic-ray test for Tracker#1 is running, and Tracker DAQ has been tested this time. Trigger counter (C 3, 4) Light-guides Cryo#1 Tracker#1 Light-guides Lead block Cryo#2 Trigger counter (C 1, 2) 2

DATE-based DAQ • By the last week, DAQ using DATE with EPICS has been checked to work correctly by the following procedures. 1. 2. 3. 4. 5. 6. 7. 8. 9. Installation of DATE package Write test code Rebuild trigger logic Take data of C 1 -4 counters with DATE Check data Take data of C 1 -4 and 8 VLSBs Check data with that taken by EXCEL Replace code of AFE with EPICS one Check data 3

Summary • Tracker DAQ based on DATE in combination with EPICS has been tested and checked to work correctly at R 8 cosmic-ray test stand. 22

Next step (R 8 XXX MLCR) • Modify readout code according to newly updated firmware (VLSB/AFE? ) if necessary. • Installing Tracker#1 in MICE Hall. • Move DAQ pc/VME crate to MLCR. • Construct trigger logic using ISIS Spill. • Test/debug • … • Take beam data (Step II. ) 23
