1. 1 DATE-based DAQ Hideyuki Sakamoto CM22, RAL 19/10/08

2. 2 R8 cosmic-ray test stand In R8, cosmic-ray test for Tracker#1 is running, and Tracker DAQ has been tested this time. Trigger counter (C3,4) Trigger counter (C1,2) Light-guides Cryo#2Cryo#1 Lead block Tracker#1

3. 3 DATE-based DAQ By the last week, DAQ using DATE with EPICS has been checked to work correctly by the following procedures. 1.Installation of DATE package 2.Write test code 3.Rebuild trigger logic 4.Take data of C1-4 counters with DATE 5.Check data 6.Take data of C1-4 and 8 VLSBs 7.Check data with that taken by EXCEL 8.Replace code of AFE with EPICS one 9.Check data

6. 6 Readout in DATE User implement following 5 functions in XXX equipment. 1.ArmXXX- called at starting run 2.DisArmXX - called at stopping run 3.AsynchReadoutXXX - called every event 4.EventArrivedXXX- called after ArmXXX 5.ReadEventXXX- called after trigger arrived User register parameters, such as base address in MySQL. User get those parameters from function’s argument. User can choose options to generate trigger and/or generate data for XXX equipment.

22. 22 Summary Tracker DAQ based on DATE in combination with EPICS has been tested and checked to work correctly at R8 cosmic-ray test stand.

23. 23 Next step (R8  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.)
