The 2002-01-01 · When using an organic liquid scintillator such as NE213 for neutron spectrometry, the light output as a function of proton energy is needed in order to unfold the neutron spectrum from the scintillator's pulse height distribution. EJ-301 and EJ-309 are liquid scintillators for neutron and gamma pulse shape discrimination (PSD). EJ-309 is specially formulated with a high flash point. The stability of each liquid in the presence of other materials should be determined before a large amount of liquid is committed.
