1. HPS TDAQ Review Sergey Boyarinov, Ben Raydo JLAB June 18, 2014

2. Requirements Up to 50kHz event rate Up to 100MB/s data rate Dead time < 1%

3. System Overview Calorimeter Readout: 442 channels of 12bit 250MHz Flash ADCs for Calorimeter (2 VXS crates, 4 ROCs) SVT readout system (1 ATCA crate, 8x2 ROCs) 85ps resolution pipeline TDCs with discriminators (2 VME crates, 2 ROCs) Total 5 crates, 22 ROCs FADC-based trigger system: 2 GTPs as crate controllers and SSP as final trigger decision JLAB CODA DAQ software

4. All modules are available Signal Distribution Sub-System Processor FADC250 Flash ADCCrate Trigger Processor Trigger Interface

5. VXS crates with FADC and Trigger boards

6. DAQ and Trigger System (with TDCs)

7. ECAL Trigger Overview FADC (Flash Analog-to-Digital Converter) 250Msps, 12bit pulse digitizer for: Readout & Trigger (energy, timing) GTP (Global Trigger Processor) Collects pulse data from all FADC channels in crate Searches for clusters on half (top or bottom) of the ECAL Sends cluster energy, time, position, hit count to SSP for trigger processing SSP (Sub-System Processor) Collects clusters from top & bottom halves of ECAL from GTP Performs cuts on individual clusters: energy, hit count Performs cuts on paired clusters: energy sum/difference, coplanar, distance-energy Delivers trigger signals to TS (Trigger Supervisor) for readout GTP 6 FADC channels available for scintillators – usable in trigger Pulses Clusters Triggers

8. CODA software (two double-roc crates test setup example)

9. Computing and network

10. Conclusion TDAQ (JLAB part of DAQ and Trigger) hardware 100% available and installed, firmware development complete CODA software is operational using recent front end libraries and CLAS-era backend Computing/network design is finished and system partially available, remaining equipment will be ordered next week and will be operational by the end of July Trigger and DAQ commissioning and testing just started and will be finished by the end of August, following by ECAL connection and testing Testing includes TDAQ event rate and data rate measurements
