Each sensor consists of a CsI scintillator, which is bonded to a shell of Pilot B plastic scintillator used for charged particle suppression.

scintillator based technology provides the high resolution requred for accurate, fast response scanning measurements.

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.

scintillator cocktail contains elements of high atomic numbers.
