Abstract
The CMD-3 detector started data taking at the electron-positron collider VEPP-2000 [1] in December 2010. The collected data sample corresponds to an integrated luminosity of 87 pb−1 in the c.m. energy range from 1.06 up to 2 GeV and 91 pb−1 from 0.32 to 1.06 GeV. The integrated luminosity was measured by counting e+e−→ e+e− and e+e−→ γγ events, allowing additional photons in the final state. Preliminary results of the luminosity measurement are presented for various energy ranges and its accuracy is estimated to be 1%.
