Abstract :
The Cornell Electron Storage Ring operates with trains of bunches that collide with a horizontal crossing angle of ±2.1 mrad. CESR has achieved a peak luminosity of 4.1×1032 cm-2 s-1 with a total current of 320 mA and nine two-bunch trains in each beam. The beam-beam tune shift parameter saturates at ξν~0.04. The current dependence of luminosity and tune shift parameter are shown. We discuss beam optics, crossing angle, injection, current limits and upgrade status
