A time-of-flight system for the external target facility

A time-of-flight system with a plastic scintillator coupled to photomultipliers is developed for the external target facility （ETF）. This system can satisfy the requirement of an ultrahigh vacuum （-10-9 mbar）, a high counting rate （-106 particles per second） and a magnetic field environment. In the...

More Information
Summary:A time-of-flight system with a plastic scintillator coupled to photomultipliers is developed for the external target facility （ETF）. This system can satisfy the requirement of an ultrahigh vacuum （-10-9 mbar）, a high counting rate （-106 particles per second） and a magnetic field environment. In the beam test experiment, a total time resolution of 580 ps FWHM was obtained for the whole system, and nuclei with a mass of up to 80 could be identified using this system.
