Recent operation status of Belle II electromagnetic calorimeter and relevant systems
The electromagnetic calorimeter of Belle II experiment consists of the 8736 CsI(Tl) crystals with their PIN-photodiode readout. Those detector hardware components have been inherited from the Belle experiment. In order for high rate capability and immunity against high beam background, waveform samp...

| description | The electromagnetic calorimeter of Belle II experiment consists of the 8736 CsI(Tl) crystals with their PIN-photodiode readout. Those detector hardware components have been inherited from the Belle experiment. In order for high rate capability and immunity against high beam background, waveform sampling readout with digital signal processing is introduced into the frontend electronics, the ShaperDSP boards. At the beginning of Belle II experiment, the COPPER system was used to receive the digitized signal output from the ShaperDSP boards, and now it is replaced by the PCIe40 system for higher throughput and maintainability. We report recent status of the Belle II electromagnetic calorimeter system including its peripheral system such as the online luminosity monitor. |
