Abstract

The SuperKEKB accelerator in Tsukuba, Japan is providing e^{+}e^{-} beams for the Belle II experiment since March 2019. To deal with the aimed peak luminosity being 40 times higher than the one recorded at Belle, a pixel detector based on DEPFET technology has been installed. It features a long integration time of 20~\mu \text {s} resulting in an expected data rate of 20 GByte/s (160 GBit/s) at a maximum occupancy of 3%. To deal with this high amount of data, the data-handling hub (DHH) has been developed. It contains all necessary functionality for the control and readout of the detector. In this article, we describe the architecture and features of the DHH system. Further, we will show the key performance characteristics after one year of operation.
