Plastic Scintillator Array

Main Plastic Scintillator array design parameters:

1. Pixel size: The X and Y dimensions of each plastic scintillator pixel

2. Separator/reflector type and thickness: The type of reflector between the plastic scintillator pixel and its overall thickness(Gap, G)

3. Pitch: The distance between the center of one element to the center of an adjacent element, X+G or Y+G

4. Radiation thickness: This is the Z dimension and specifies the thickness of the array in the direction of incoming radiation

5. Back reflector thickness: Usually a white reflector is applied to the radiation entrance side of the array to reflect the light

   back into the pixel so it can be directed to the photodetector

6. Separator/Reflector: Barium Sulfate(BaSO₄)
