  • Abstract
    A new dual rectangular photomultiplier tube (PMT) developed for the positron CT is discussed in comparison with the conventional small-diameter PMT. A matching in shape between the scintillator and the PMT is an important factor to obtain good time resolution. The new PMTs have coincidence time resolution less than 3 ns in FWHM coupled to 12 mm (wide) x 24 mm (high) x 24 mm (long) BGO scintillators for 511 keV annihilation ¿-rays while resolution of the conventional small-diameter PMTs is around 5 ns in FWHM.
