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

  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) Light-guides Light-guides Tracker#1 Cryo#1 Cryo#2 Lead block Trigger counter (C1,2)

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

  6. Readout in DATE • User implement following 5 functions in XXX equipment. • ArmXXX - called at starting run • DisArmXX - called at stopping run • AsynchReadoutXXX - called every event • EventArrivedXXX - called after ArmXXX • 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.

  7. Our equipments a b c d e f • SBS VME bus adaptor • CAEN V977 I/O Register • CAEN V792N QDC (16ch-lemo) • MIL-1553 • VLSB Trigger module • VLSB module From AFEIIt From C1-4

  8. Equipments in DATE Type : Number to identify the equipment D : GENDATA T : GENTRIGGER #/pars. : Number of parameters registered in MySQL

  9. Start run • AFE 1. Check if AFEIIt boards are configured • If no, run stop, and • User configures boards using EPICS ConfigurationUI. 2. Enabling trigger of AFE boards by EPICS

  11. Decoding • Following data are recorded. • ADC of trigger counters (4 channels) • Temp/Heater of 4 cassettes (32 channels) • ADC/TDC of 8 VLSBs (4096 channels)

  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. 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.)
