The energy reconstruction algorithm for high injection background
for Belle II electromagnetic calorimeter group
Published online: 7 March 2025
The SuperKEKB e+e− collider is operated with the continuous injection that tops up the beams during colliding beam operation for physics data taking to maximize integrated luminosity. When the beam bunch is injected to the collider ring, there is an unavoidable disturbance by the injected bunch. At the Belle II electromagnetic calorimeter, countermeasure for the injection background using the detector’s waveform readout data is being considered. We report its concept and recent development status.
