Abstract：
The prototype with cell and layer design of BES main drift chamber has been built and tests of the prototype on K2 Test Beam of KEK Proton Synchrotron have been made with 0.5～1.5GeV/c e⁺,π⁺, and p beams. The spatial resolution for single wire of σ_x=170～210μm has been obtained within cell half width of 3.1cm. The energy resolution σ_E/E corresponding to 40dE/dx samplings of 1 cm is about 15%.
