EJ-276 pulse-shape discriminating (PSD) plastic scintillator enables the separation of gamma and fast neutron signals on the basis of their timing characteristics. This scintillator replaces all versions of EJ-299-33 and EJ-299-34 PSD scintillators and embodies the following improvements:
Excellent physical hardness, equal to or superior to that of standard plastic scintillators
Long-term stability of scintillation and optical characteristics
Basic PSD properties increased to being comparable to the best liquid scintillators
EJ-276G with green fluorescence is also available for use with solid-state sensors.
