Description
The design luminosity of the SuperKEKB collider in the BelleII
experiment at KEK is $8\times10^{35}$ $\rm{cm}^{-2}\rm{s}^{-1}$ or
40 times larger than that of the previous KEKB collider with the
Belle detector. Correspondingly, one expects larger beam background.
also increased. To keep performance of the electromagnetic calorimeter
at the high level, a new readout scheme has been developed
and implemented in new detector electronics.
The new scheme provides continuous digitization of shaped signal followed by
wave form analysis with determination both amplitude and time of the
signal.
Time allows essential suppressions of background hits.
We performed study of hits reconstruction algorithm and developed
calibration tools for Belle-II calorimeter using background simulation
data and cosmic rays events.
