Abstract
We have tested several types of TOF counters based on scintillators an d photomultiplier tubes in order to measure the lifetime of hypernucle i. With the advantage of small counter size, we obtained less than 30 ps timing resolution, and about 50 ps overall TOF resolution. The vari ous factors in this resolution have been studied. The timing resolutio n dependence on the beam intensity is also studied.
