Abstract

A BGO array coupled to the PSPMT (Position Sensitive Photo- Multiplier Tube) is used as the image system to identify the position of the scintillation event. The newly developed PSPMT R5900-00-C8 (Hamamatsu Photonics, K. K) with metal channel dynodes and 8 cross plate anodes is the key component to determine the location and the energy of the scintillation event. The imaging instruments are arranged as follows: BGO array is coupled to the PSPMT. Each of the eight anode signals generated by the PSPMT (4 for X dimension and 4 for Y dimension) are amplified and offset-compensated. A trigger module provides a proper trigger and gating signal for the ADC module. A delay device is inserted between each output of the preamplifier and the input of the charge integrating ADC to adjust the timing delay introduced by the trigger module. The digitized signals captured by the ADC are recorded and processed by computer to locate the energy and position of the scintillation events. The imaging characteristics of the BGO- PSPMT combination have been evaluated. Results suggest that this imaging device may be very useful in applications requiring high spatial resolution radiation detection by a compact imaging device.
