Abstract
A large number of decodable crystals per photomultiplier tube (PMT) can be achieved using the PMT-quadrant-sharing (PQS) technique with proper optically 1 reflecting windows to channel light distribution in scintillation detector block However, to develop brand new optically decoding reflecting windows for a detector block with different crystal material, PMT size or decoding resolution, is still very time-consuming and also requires much experience. This study is to develop a computer software tool that can simulate an expected 2-dimensional crystal decoding map before implementing a real detector block with a new set of decoding reflectors. After comparing the experimental decoding data to the simulated results with the same reflector set, data are feed to adjust the software parameters. More accurate decoding reflectors will then be created using the adjusted parameters. A 13 × 13 detector block was evaluated and our preliminary study shows this simulation tool is very promising which can significantly reduce a new product developing time; only a few development cycles are needed to get to the final optimized decoding reflectors.
