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)

Global Belle II DAQ(COPPER to storage) Actjvitjes of data-taking towards Global CRT Pocket DAQ in E-hut  Backend DAQ is fmexible for standalone or combined cosmic data tests.  FTSW : one combined CRT + standalone CRTs. PocketDAQ of each det. Gr. (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 S.Yamada DESY VXD by global DAQ system is possible. Beam test?

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(?).

Live CDC event display - 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. 2 PXD sensors track reconstructed by HLT RoIs obtained from tracks

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
