BEAM TESTS OF THE PROTOTYPE OF BES MAIN DRIFT CHAMBER

    Corresponding author: MA Ji-Mao,

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++, and p beams. The spatial resolution for single wire of σx=170~210μm has been obtained within cell half width of 3.1cm. The energy resolution σE/E corresponding to 40dE/dx samplings of 1 cm is about 15%.
