Description

The future Belle II experiment will reach a total luminosity of $8\cdot 10^{35} cm^{−2} s^{−1}$. With such high luminosities, the innermost detector, the Pixeldetector (PXD), will produce raw data rates of up to 20 GB/s. In order to reduce these rates, a high bandwidth data aquisition and data reduction system for the PXD is required. The so-called ONline SElection Node (ONSEN)-system will consist of 32 ATCA based Com- pute Nodes (CN) with Xilinx Virtex-5 FPGA’s. These will perform a Region Of Interest (ROI) selection based upon online track extrapolation from the outer detectors. A reduction factor >10 is planned. We present recent tests of a reduced ONSEN setup, with data taken during a testbeam campaign at DESY as well as a high bandwith lab-test with the full setup.
