New position sensitive photomultiplier tubes for high energy physics and nuclear medical applications
New position sensitive photomultiplier tubes with fine mesh structured dynodes and discrete anode array configurations have been developed. One kind of the position sensitive photomultiplier tubes is being used as a photodetector for High Enegy Physics applications in high magnetic field environments. A photomultiplier tube constructed with 88 Multi-Anodes has a spatial resolution of less than 2.6 mm in FWHM in a magnetic field with a density of 500-2000 Gauss. The resolution includes an anode width of 2.6 mm. Another type of Multi-Anode photomultiplier tube which has been developed is the detector with a high spatial resolution for such applications as the PET system and hodoscope in scintillation systems. The tube, by applying additional electro-focusing electrodes, has an intrinsic spatial resolution of 1.4 mm in FWHM without the magnetic field.
