  1. Detector DAQ And Trigger Status Jean-Sebastien Graulich, Geneva • Achievements Since CM21 • Detector DAQ Status • Trigger Status • Online Software • Front End Electronics • Schedule Milestones • Summary Jean-Sebastien Graulich

  2. Reminder DAQ related activities • Front End Electronics • Transmission and digitization of analog data, • Readout hardware • VME crates and boards, network in LCR • Readout Software • Data transfer from FEE to disk • DAQ Human Interface • Start and stop run, change configuration • Trigger Logic and Electronics • Synchronize DAQ with target, generate and distribute trigger signals to FEE. • Data unpacking and interface with Analysis software (G4MICE) • Contribute to Online Reconstruction by hardware (CPU) and software • Online monitoring • Produce histograms relevant for data quality checks, provide graphical interface to display them • Permanent data storage • Produce software to archive data from Online disk buffer to Atlas center Running the Human Interface is left to the user… Jean-Sebastien Graulich

  3. Achievements since CM21 CKOV, KL, TOF0 are included in the DAQ Scalars counting relevant rates are included in the DAQ DAQ, Trigger and Online Monitoring systems have been used successfully • Commissioning is well advanced but the systems are still evolving • Interesting data has been taken (see tonight) Consolidation of the hardware • Major revision of the hardware installation and cabling DAQ and Particle Trigger • DAQ trigger scheme implemented according to final design • TOF0 included in Particle Trigger Documentation has been improved Jean-Sebastien Graulich

  4. Detector DAQ Status Readout Code for TDC V1290, flash ADC V1724 and Scalar V830 • Now fully commissioned. Several bugs have been corrected in July Readout Code for Tracker VLSB • See Hideyuki’s talk No progress yet on the interface with EPICS One major change in the design • It is proposed to include the target data (digitized target position and Beam loss signals) in the system like any other data source Jean-Sebastien Graulich

  5. Target DAQ Progress in Integration of the Target Data into the DAQ A technical solution has been agreed on togetherwith the target group No additionalcost No risk of failureinvolved Basic idea: The target group willprovidereadout code for the new I/O card The DAQ group willprovideunpacking and online monitoring code Discussion with the software group on how to includethis data in G4MICE (Spill based data ≠ particlebased data) took place. Implementationisunderway. The targe DAQ PC willbefullyintegrated in the Detector DAQ Jean-Sebastien Graulich

  6. Target DAQ Plan Milestones for Integration of the Target Data into the DAQ The new NI I/O Card is installed into mice2, and tested Done A VME-PCi interface CAEN V2718 is inserted into mice2 Doneand the driver is installed ISIS signals and analog Target Position signal are plugged Doneinto the NI/IO card DATE is installed and running on mice2 (not connected to DDAQ) Sept 22 Installed but not running yet The target group delivers the software for the stand alone Donereadout and monitoring Stand alone monitoring of ISIS signals and Target Position ~Done is demonstrated DAQ group delivers the software for the DATE readout and Oct 13online monitoring mice2 is included in the DDAQ system and the target data is readout Oct 20 Online Monitoring of ISIS signals and Target Position inside Oct 27 DDAQ is demonstrated New target date isNov 4 Jean-Sebastien Graulich

  7. Trigger Status Interfacew/Target & Spill Gate DAQ Trigger distribution KL Scalars and particle trigger NIM Logic Shapers GVA Discri, KL cosmics trg TOF & CKOV TOF discriminators and trigger CAMAC Logic New CrateLayout Jean-Sebastien Graulich

  8. DAQ Trigger Four types of DAQ triggers - PHYSICS - CALIBRATION - Start of Spill - End of Spill Event Type istagged in the data header Used to impose a well-definedsequence of events and online check of synchronisation Jean-Sebastien Graulich

  9. DAQ Spill Gate Detailed documentation of the procedure to adjust the DAQ Spill Gate has been produced and tested with MOM Machine start after delay in the target system Spill Gate is always aligned to extraction Jean-Sebastien Graulich

  10. DAQ Spill Gate Hits in GVA1 Machine Start DAQ Gate ~ 3.5ms Jean-Sebastien Graulich

  11. Particle Trigger Particle trigger has been upgraded to allow easy selection of trigger condition Now a pressbuttonoperation, no cable swapping Detailed documentation written and testedwith MOM Available Trigger Conditions 1) Any logical OR combination of the GVA counters: [GVA1] [OR GVA2] [OR GVA3] 2) Any logical AND combination of the GVA counters: [GVA1] [AND GVA2] [AND GVA3] 3) TOF0 4) The logical AND combination of 1) or 2) with TOF0 The particle trigger signal is sent to channel 0 in each TDC Jean-Sebastien Graulich

  12. TOF0 Logic TOF0 signal is the OR over all the slabs of the AND of the two pmts of each slab Because of hardware constraints, Wealsodefine TOF0_H: OR over 8 central H slabs TOF0_V: OR over 8 central V slabs TOF0_EXT: OR over the 4 frame slabs TOF0 has 40 channels • 10 horizontal slabs • 10 vertical slabs • 2 PMts per slab Jean-Sebastien Graulich

  13. TOF0 Logicimplementation TOF1 will be included in the trigger in a similar way Jean-Sebastien Graulich

  14. Burst Gate Reminder The burst corresponds to the micro structure of the beam Proton bunches crossing passing throght the target ~100 ns repeating every 324 ns (at the end of the accelration cycle) The ISIS beam position monitors can be used to materialize the burst structure Envelope of Beam Position monitor in Sector 7 (sum) Jean-Sebastien Graulich

  18. Burst Gate Correlation GVA1 hit Burst Gate made narrow Jean-Sebastien Graulich

  19. Online Software Unpacking libraries have been extensively tested and work fine • Upgrade for Tracker will be needed soon Online Monitoring is now working really online • A list of available histograms with description exists Recent developments focused on the interface with G4MICE (see Software session for more details) • Basic architecture is now in place • First task is to reproduce online histograms Jean-Sebastien Graulich

  20. Scalar in DAQ Part. Trg Req. Cumulative, average and Last Spill Available TOF0 GVA2 CKOVA/B GVA1 Part. Trigger Clock 1MHz GVA3 Scalars count hits inside the DAQ Spill Gate (independently from trigger conditions) Jean-Sebastien Graulich

  21. Scalar Histograms Jean-Sebastien Graulich

  22. Front End Electronics CKOV It has been recognized that CKOV FEE should sustain a much higher instantaneous rate than other detectors (no segmentation) Shaper + 100 MHz fADC not appropriate New 500 MHz fADC have been ordered and is at RAL. Will be installed this week. There will be no more TDC data for CKOV TOF TOF TDCs are not properly synchronized. Internal clock has to be distributed. For the moment, we use the common Part. Trigger signal in ch0 of each TDC TOF1: Electronics is hand TOF2: We miss some electronics Shapers: In production; expected for December 2008 TDC: One board missing FADC: 3 boards missing SW Was discussed in PID session Jean-Sebastien Graulich

  23. FEE Issues Cross Talk Issue The Splitters introduce cross talk between TOF channels Splitter prototype did show this effect We understand this is caused by the additional grounding plane we have added to suppress pick-up noise We need to understand the effect on TOF and CKOV performances (KL is not affected) New design is under study FADC firmware upgrade Needed to allow significant reduction of data volume Less samples per Particle event (currently 512 whereas only 60 are necessary Zero suppression (to be tested) Delicate operation Jean-Sebastien Graulich
