摘　　要：本文介绍了北京正负电子对撞机(BEPC)上的试验束的初级束的研制;报道了次级束的产生和次级束中正电荷粒子的鉴别与测量;简单介绍了利用试验束进行的量能器模块的辐照损伤研究。This paper reports the design and construction of the primary beam of the test beam on BEPC, as well as the acquirement of the positive-charged secondary beam, and the various particles, e^+,π^+,μ^+, p, in the secondary beam have been measured with TOF method and threshold Cherenkov counter. The radiation damage studies of SDC calorimeter modules using the test beam have also been briefly described.
