Belle II DAQ System

Belle II Schedule

• The operation of SuperKEKB accelerator had been started from the

beginning of this year although the beams are not yet collided.

• “BEAST” detector was implemented in the IP to monitor the

background level June 18, 2016 (LER beam current at 970 mA, HER at 870 mA)

• Backend DAQ is fmexible for standalone or combined cosmic data tests.
• FTSW : one combined CRT + standalone CRTs.

(Except for CDC. It can be combined with another sub-detector like CDC+TOP)

• > As for backend DAQ and TTD(not trigger source), combined CRT

by global DAQ system is possible. install Combined CRT for some sub- detectors? Pre-GCRT period

Note : Each tjmeline is not precise. It depends on sub-detector’s installatjon/commissioning schedule.

DAQ status

• DAQ integration of outer detectors is in progress.

+ Detectors integrated in structure: * ECL (barrel) - Completed and stably running with the global Belle II DAQ. * KLM (barrel) - Being tested with Pocket DAQ. Firmware debugging in progress. * TOP - All installed modules are being tested using Pocket DAQ(stand-alone DAQ), module by module basis. Integration in Belle II DAQ is in progress. + Cosmic ray data taking with Pocket DAQ is going on for all installed modules + Feature extraction firmware (TOP) is still under debugging. + CDC test stand: * A separate Belle II DAQ is prepared. * The cosmic ray data taking with 60 FEE modules is stably running. * One TOP module is installed near the CDC for the test in the cosmic ray with a tracking information. * The data stream from TOP is combined with the CDC data stream and the data taking is started.

• > The ending date of data taking was enlonged to Sep(?).

• Full readout chain confirmed to work:

FEE->COPPER->Readout PC-> HLT processing (Unpacker)

• > Storage(sampling) -> Express Reco -> evdisp

• VXD integration was tested in DESY test beam

+ The DESY test beam DAQ was fully operational and worked stably up to 2 kHz in beam. + The Run Control was fully implemented with both SVD and PXD readouts. + “Event mixing” was observed inside both of SVD readout (FTB) and DHE/DHC/ONSEN in PXD readout, although the event mis-match at event builder 2 was not occurred. * Event numbers are properly distributed to detectors from FTSW which are embedded in the raw data header of each detector data. * Event numbers embedded in the raw data body in PXD/SVD were mis-matched.

• > Investigation by both PXD and SVD FEE experts is being done.

+ The RoI feedback from HLT to ONSEN was confirmed to work. * Because of channel mismatch between DHP and DHE, the remapping had to be implemented, which could not be completed during beam test.

• > Had to use large-size RoIs.

Goals of this workshop (for DAQ)

• Discussion on the status and problem in the further

detector integration * TOP <- On-going top-priority issue. * KLM <- When can we integrate in global DAQ? Urgent issue. * ARICH * Endcap ECL

• Prospects for GCRT (Global Cosmic-Ray Test)

* Trigger for GCRT * Schedule : What detectors in DAQ?, Detector Roll-in schedule.

• Preparation for Phase II run

* Test of VXD readout at DESY-TB * Issues in DAQ preparation for Phase II run. * DAQ configuration for Phase II
