本文描述了飞行时间(TOF)技术作为Hermes实验的粒子识别方法的使用。TOF是由两个最初仅为一级触发而设计的1×4m2闪烁示波器测量的。然而，HERA电子束的合适的时间结构允许扩展它们的功能，以测量用于识别低动量强子的TOF。仅用这些常规的望远镜，对动量范围高达2.9GeV/c的质子和介子，以及动量范围高达1.5GeV/c的Kaon，都取得了良好的粒子识别效果。
This paper describes the use of the time-of-flight (TOF) technique as a particle identification method for the HERMES experiment. The TOF is measured by two 1×4m2scintillation hodoscopes that initially were designed only for the first-level trigger. However, the suitable time structure of the HERA electron beam allows an extension of their functions to also measure the TOF for low momentum hadron identification. Using only these conventional hodoscopes, good particle identification was achieved for protons and pions in the momentum range up to 2.9GeV/c and for kaons up to 1.5GeV/c.
