Guardian™ Glass leverages Lithium-6 fiber neutron detector technology for thermal neutron detection, neutron radiography, oil well logging, neutron and/or gamma detection, chromatography, and research. Our 6Li fiber neutron detectors represent the first compelling new technology for thermal neutron detection since the initial 3He and 10BF3 tubes. The key advantages of 6Li glass over gas tubes are their sensitivity, fast timing, and dynamic range.
