6Lil(Eu) Detector



Rigol's 6Lil(Eu) Detectors have a high neutron cross-section as well as high light output.


  • High neutron cross-section
  • High light output
  • 3 mm LiI(Eu) stops 90% of thermal neutrons
  • Rugged crystal (> 20 degrees C gradient / hour allowed)
  • Excellent neutron / Gamma discrimination (neutron peak > 3 MeV)
  • Neutron peak resolution <7% FWHM (PMT readout)


  • Thermal neutron detection
  • Spectroscopy

Neutron Detection

Neutrons do not produce ionization directly in scintillation crystals, but can be detected through their interaction with the nuclei of a suitable element. In a 6 Lil(Eu) scintillation crystal for example, neutrons interact with 6 Li nuclei to produce an alpha particle and a triton (tritium nucleus), which both produce scintillation light that can be detected. For this purpose, enriched 6 Li-containing glasses can be used, doped with Ce as activator.
