AB - In order to measure integrated luminosity with the required precision of $10^{-4}$ at the $Z^0$ pole, the proposed CEPC $e^{+}e^{-}$ collider requires a luminometer, a specially designed calorimeter placed in the very forward region to identify Bhabha scattering at low polar angles. Usually, such a device is placed at the outgoing beams, to keep the spatial symmetries of the head-on collisions at accelerators with a nonzero crossing angle. At CEPC it is currently proposed to place the luminometer on the z-axis. We review the feasibility of measurement of the integrated luminosity at the $Z^{0}$ pole with the required precision, focusing on the luminometer centered around the z-axis and the post-CDR beam properties.
