Stilbene is an organic solid scintillator material used for fast neutron detection.

Characteristics:

• Direct detection of fast neutrons
  • Stilbene is highly sensitive to fast neutrons, hence they do not need to be moderated to lower energies to be detected
  • Stilbene takes advantage of the low background of fast neutrons for low-noise measurements
  • Detection of unmoderated neutrons preserves information about neutron trajectories and energies

• Excellent discrimination between neutrons and gamma rays
  • Facilitates counting fast neutrons without false positives from gamma rays
  • Permits use of lower energy thresholds than liquid scintillators

• Safe and Easy to Handle and Transport
  • Solid, non-hygroscopic, not flammable, not hazardous
  • Unpackaged stilbene is stable
  • Avoids the transportation, storage, and handling concerns of many liquid organic scintillators
