Description
SuperKEKB electron-positron collider utilizes continuous injection to get the world highest luminosity for the Belle II experiment. The injected bunch becomes the source of extra background for 10-20 ms duration and crosses the interaction point (IP) every 10 microsec. To reconstruct energy deposition and timing of the incident particle, the Belle II calorimeter uses the waveform sampling readout during about 17 microsec and the injection background hits can deteriorate the energy resolution. We performed the simulation of the injection background effects and developed the algorithm modification which makes the energy reconstruction immune for high injection background. We present the simulation results and test of the algorithm with experimental data.
