Neutron Detector Based on Gas-Filled Glass Shells
A New Class of Neutron Detectors: gas-based detectors with breakthrough performance for detection of illicit neutron source
Performance:
- High neutron detection efficiency - dispersion of shells in moderator
- Low gamma contamination - short internal dimensions
Manufacturability (commercialized):
- Holds high pressures
- Mechanical integrity
- Shells fabricated at high volume and low cost
