Crosstalk in Scintillating Fiber Array Detector Irradiated by Highenergy Xray
The crosstalk in plastic scintillating fiber array detector with highenergy gamma incident was studied through MonteCarlo simulation. The relationship between crosstalk and lead layer was also analyzed. Modulate transfer function(MTF),which shows quantity of spatial resolution of imaging detector, was analyzed and compared in order to get the MTF results caused from the difference thickness of lead layer. The results show that there exists severe crosstalk in the detector irradiated by highenergy particles, and the lead layer can reduce the effect. On the other hand, the pixel of detector may become big as the lead layer is introduced, which can reduce the spatial resolution. Through the simulation computation, it is proved that the right thickness of lead layer will reduce crosstalk and increase spatial resolution of imaging detector.
