Description
The Maximus Energy 3He Neutron Detector is highly sensitive to thermal neutrons and an excellent choice for professional researchers and enthusiasts alike. Helium-3-filled proportional counters are characterized by the highest sensitivity to thermal neutrons across all neutron detector classes, making them indispensable for:
- Thermonuclear fusion research & development
- Nuclear reactor monitoring and control (neutron flux measurement, reactor protection)
- Nuclear safeguards and nonproliferation (fuel inventory, diversion detection)
- Radiation portal monitors and border security (detection of illicit nuclear materials)
- Homeland security and counterterrorism (searches for concealed fissionable sources)
- Neutron activation analysis (elemental/trace analysis in archaeology, geology, forensics)
- Oil, gas, and hydrocarbon logging (neutron porosity logging, reservoir characterization)
- Well logging for mining and petroleum (formation evaluation, moisture/porosity)
- Soil moisture and hydrogeology surveys (neutron moisture gauges for bulk water content)
- Neutron radiography and imaging (industrial inspection, material defects, flow visualization)
- Medical isotope production monitoring and quality control
- Radiation protection and dosimetry (neutron dose monitoring in workplaces)
- Neutron scattering instruments (beam monitors, flux normalization in research reactors, and spallation sources)
- Particle physics and nuclear physics experiments (neutron detection in detectors, beam diagnostics)
- Fusion research (neutron yield measurements, diagnostics for tokamaks and inertial fusion)
- Spacecraft and planetary science (cosmic-ray/planetary neutron detectors for composition and hydrogen/water detection)
- Environmental and climate studies (cosmogenic neutron soil moisture mapping, snowpack measurement)
- Industrial process control (monitoring thickness, composition, or moisture in manufacturing)
- Waste management and characterization (radioactive waste assay, fissile material detection)
- Criticality safety and accident response (criticality monitoring and post-accident surveys)
- Anti-submarine and naval applications (underwater neutron sensing, reactor monitoring on vessels)
- Neutron coincidence and multiplicity counting (assay of plutonium and mixed-oxide materials)
- Active interrogation systems (induced fission detection using neutron sources)
- Security screening in ports and cargo inspection (container scanning, augmenting gamma systems)
- Educational and training purposes (laboratory demonstrations, detector development)
- Low-energy nuclear reactions (LENR) research & development
- General nuclear science research.
Maximus Energy 3He Neutron Detector is compatible with most MCA/DPP systems. To build a complete neutron spectrometer, connect the detector to the MCA-LITE and use the PulseCounter Pro spectroscopy software to acquire a neutron spectrum and counts.
