<p>A method for high energy ray probing and locating is provided. First, scintillation crystals for capturing high energy ray are arranged into a regular array; a plurality of photomultiplier tubes (PMTs) of different sizes are assembled into combined arrangements so that PMTs of smaller sizes are located in the center of PMTs of larger sizes; the scintillation crystals array is bonded with a composite PMT array with optical cement, obtaining combined detectors for high energy ray; scintillation lights are generated when high energy gamma rays are incident upon the scintillation crystals array of the above combined detectors for high energy ray, electric pulse signals are obtained after the scintillation lights are multiplied by the composite PMT array, and then the electric pulse signals are processed to obtain information like, a coordinate of high energy ray in the scintillation crystal array, energy and time. The method of present invention provides high energy ray detection with higher efficiency and more uniformity, and the method has higher spatial resolution, higher energy resolution and, in the mean time, quick responses.</p> |
