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.展开更多
