Each sensor consists of a CsI scintillator, which is bonded to a shell of Pilot B plastic scintillator used for charged particle suppression.
A test counter to study the Gd loaded liquid scintillator has now been built and tested.
Calorimeters made from a plastic scintillator, themselves connected to photo-multiplier tubes, cover the external walls of the tracking volumes.
Once again, unique scintillator based technology provides the high resolution requred for accurate, fast response scanning measurements.
The non-linear correction required to simulate low-energy X-ray photoabsorption is basically important when the scintillator cocktail contains elements of high atomic numbers.
