摘要：

A half-size prototype of the multi wire drift chamber for the cooling storage ring external-target experiment(CEE) was assembled and tested in the 350 MeV/u Kr + Fe reactions at the heavy-ion research facility in Lanzhou. The prototype consists of six sense layers, where the sense wires are stretched in three directions X, U, and V; meeting 0?, 30?, and-30?,respectively, with respect to the vertical axis. The sensitive area of the prototype is 76 cm × 76 cm. The amplified and shaped signals from the anode wires were digitized in a serial capacity array. When operating at a high voltage of 1500 V on the anode wires, the efficiency for each layer is greater than 95%. The tracking residual is approximately 301 ± 2μm. This performance satisfies the requirements of CEE.
