Abstract content

The construction of the SuperKEKB electron-positron collider and upgrade of the Belle II spectrometer are going on at KEK aiming at high precision measurements in bottom, charm and tau flavor sectors. We describe a replacement of the electronics for the CsI(Tl) crystal calorimeter with PIN-PD readout to match the luminosity increase up to 800/(nb·sec) at maximum. A plan to replace CsI(Tl) crystals with pure CsI in the endcaps is also mentioned.
