Description
The CMD-3 detector has taken data at the electron-positron collider VEPP-2000 since december 2010. The collected data sample corresponds to an integrated luminosity of 180 pb$^{-1}$ in the c.m. energy range from 0.32 up to 2 GeV. The integrated luminosity was measured by counting $e^+e^- \to e^+e^-$ and $e^+e^- \to \gamma\gamma$ 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%.
