Abstract：
Beam test results of the 45 degree prototype of the central drift chamber for BES using 0.5 and 1.0GeV/c e⁺,π⁺ and p provided by beam K2 at the KEK 12GeV proton synchrotron in Japan are described.The spatial resolution is about 160μm.The integrating nonlinearity of position sensing of charge division is better than 0.5%.The resolution in z direction is 2.3% at the middle of sense wire when the output charge is 1.4±0.2pC.
