N2 - To provide real-time luminosity values in the Belle II experiment at the SuperKEKB collider, the standalone system was designed. It evaluates luminosity from counting rate of Bhabha and two photon annihilation events based on the Belle II electromagnetic calorimeter information. At the design luminosity of 6×1035 cm−2s−1 the system will provide a counting rate of 18 kHz with systematic accuracy of 0.8% and statistical accuracy of 0.7% for the one second integration time. For the currently achieved luminosity, the statistical accuracy is 2.6%.
