摘　　要：研制成功的（ｅ，２ｅ）实验的符合测量系统由快时间道和慢位置道组成。以该系统四个慢符合道的位置信息电荷脉冲信号和快符合道中的时间信息作为五个参数。测得了电子碰撞Ｈｅｌｓ的符合时间谱和电离能谱。A newly developed coincidence measurement system used for (e,2e) experiments is described. It consists of a fast timing channel and four slow position channels. The five parameters acquired by the system are four position charge pulses from slow channels and a timing pulse from TAC. The He(e,2e) He+ 1s experiment has been carried out by using this system, and the coincidence time spectrum and binding energy spectrum were obtained.
