NeuPortTM and NeuTruckTM solutions provide a cost-effective plug-and-play replacement to He-3 for portal and vehicle-mounted monitors. These are 6LiF/ZnS(Ag) based flat packaged neutron sensitive detectors contained in a high-density polyethylene moderator enclosure. Neutrons are captured by the 6Li and the reaction products excite emission from the ZnS(Ag) scintillator which in turn is absorbed in an adjacent ribbon of wavelength shifting fiber.
Proprietary Pulse Shape Discrimination (PSD) algorithm is employed to count neutrons and reject gamma-ray events.
Plug & Play Replaces He-3 systems without modification of existing electronics or significant changes in voltage
Value Provides performance that meets or exceeds ANSI standards
Safe Contains no hazardous materials and does not require secondary containment
Reliable Is based upon well-established technologies that guarantee product reliability over time.
Fully Integrated Incorporates the electronics that allows calibration to meet specifications
