贝儿飞行时间系统提供π/K分离的粒子动量低于1.2 GeV/c。在KEKB高速环境下,采用了一种新的时间展宽TDC测量方法,测量最低有效位(LSB)为25 ps的飞行时间。TOF分辨率为100 ps。TOF系统还为贝儿触发系统提供精确的事件定时。(C)2000 Elsevier Science B. V.保留所有权利。
The BELLE TOF system provides pi /K separation for particle momentum below 1.2 GeV/c. A novel Time Stretcher TDC scheme is used to measure flight times with a 25 ps LSB in the high rate environment of KEKB. The TOF resolution is found to be 100 ps. The TOF system also provides precise event timing to the BELLE trigger system. (C) 2000 Elsevier Science B.V. All rights reserved.
