Development of FPGA-Based Algorithms for the Data Acquisition of the Belle II Pixel DetectorPublic
The pixel detector and Belle II data-acquisition systems impose various re- quirements on the performance of the ONSEN system, including a data through- put of almost 600 MB/s and a memory bandwidth of about 1 GB/s for every of the 32 modules performing the data reduction. The ONSEN system uses high-speed serial I/O links and low-level memory-cont… |

Development of the Online Data Reduction System and Feasibility Studies of 6-Layer Tracking for the Belle II Pixel DetectorPublic
A first test with the whole DAQ integration and prototype sensors of PXD and SVD had been performed at DESY. For the verification of the ROI selection logic a full recording of in- and output data was included. With this setup I recorded 1.2x10^6 events containing in total 4.8x10^8 hits. The occupancy of originally ≈ 0.80% was reduced with my ROI … |

Study of improved K_S^0 detection for the Belle II DetectorPublic
In this work, an online tracking algorithm is developed and evaluated focusing on the reconstruction of charged pions from displaced vertices, the characteristic decay topology of K_s^0 mesons. All six VXD layers are used. The algorithm, which may be used on the FPGA-based PXD DAQ system, is based on the fast Hough transform applied to the hits ma… |

Particle identification devices at the Belle II experimentPublic
Particle identification at the Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, is provided by two ring imaging Cherenkov devices, the time of propagation counter in the barrel and the proximity focusing RICH with aerogel radiator in the forward end-cap region. They are expected to provide kaon identification efficiency of more tha… |

Track Fitting in Belle II: the Genfit Library and its PerformancePublic
We discuss track fitting as implemented in the Belle II experiment currently under construction at KEK in Tsukuba, Japan. Track fitting takes place at the interface of physics analysis and detector data, is essential to the tasks of detector calibration and alignment, and it also is an integral part of Belle II’s high-level trigger. To address thi… |

Grid Computing at Belle II Public
The Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, will start physics data taking in 2018 and will accumulate 50 ab−1 of e+e− collision data, about 50 times larger than the data set of the earlier Belle experiment. The computing requirements of Belle II are comparable to those of a run I high-pT LHC experiment. Computing will mak… |

Trigger and Data Acquisition Systems at the Belle II ExperimentPublic
Both the trigger and the data acquisition systems of the Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, are completely redesigned to cope with the considerably higher event and background rates compared to the previous Belle experiment. Belle II hardware (Level-1) trigger consists of several sub-triggers and a final decision logi… |
