The purely software based old data acquisition system of the COMPASS experiment at CERN is replaced by the new hybrid FPGA-software system. The two level FPGA subsystem takes over the data handling role. The hardware is built in a compact AMC form factor using a Xilinx Virtex-6 VLX130T FPGA as a data processor. The data handling includes a 15:1 data link multiplexing and complete event building in...
The Belle 2 experiment is undergoing an upgrade with the aim to perform the most precise measurement of the CP-violation using the state-of-the-art detectors. The silicon pixel detector is the innermost layer of the experiment. Because of the increased beam background and the high detection efficiency of the silicon pixel detector, the data rate of the detector is estimated at 22 GB/s which is 10...
The upgrades of the Belle experiment and the KEKB accelerator aim to increase the data set of the experiment by the factor 50. This will be achieved by increasing the luminosity of the accelerator which requires a significant upgrade of the detector. A new pixel detector based on DEPFET technology will be installed to handle the increased reaction rate and provide better vertex resolution. One of...
