英文摘要A prototype of the BESIII drift chamber was tested with He/C3H8(60/40) gas mixture in a IT magnetic field at the pi-2 beam line of KEK 12 GeV PS. The drift distance-time relationship was extracted for various conditions. The performance of the chamber, such as the spatial resolution, the dE/dx resolution and the cell efficiency, was studied in detail. The dEldx was measured as a function of beta gamma to calculate the particle separation power. Based on the test results, the operating voltage of the BESIII drift chamber is optimized to be 2200 V, resulting in a spatial resolution better than 110 mu m, a cell efficiency over 98%, a dE/dx resolution better than 5% and the 3 sigma pi/K separation at a momentum exceeding 700 MeV/c. These results confirm the validation of the physics design of the BESIII drift chamber. (c) 2005 Elsevier B.V. All rights reserved.
