Abstract The main characteristics of coherent bremsstrahlung (CBS) for the Beijing Electron-Positron Collider are calculated. At this collider dNγ~3 x 108 dEγ/Eγ photons of CBS will be emitted for a single collision of the beams in the energy range Eγ< 240 eV. It seems that CBS can be a potential tool for optimizing collisions and measuring beam parameters. Indeed, the bunch length σz can be found from the CBS spectrum because critical energy Ec ∝ 1/σz; the horizontal transverse bunch size σx is related to dNγ∝1/σx2. In addition, CBS may be very useful for a fast control over an impact parameter R between the colliding bunch axes.
