Helium-3 Detector

Reuter-Stokes designs and manufactures neutron detectors and gamma radiation sensors for applications ranging from homeland security, nuclear reactor monitoring and safeguards, material science research and even space exploration!

Our advanced manufacturing allows us to match the exact performance of any Helium-3 (3He) proportional counter, regardless of age. This revolutionary process helps save you time and reduce costs.

Purification techniques and manufacturing process control were developed to ensure precise matching of operating characteristics among large batches of counters. This permits parallel operation of large numbers of detectors without the need for separate power supplies or gain matching.

Gas mixtures can be tailored for a customer’s applications and for optimization of combined parameters, including operating voltage, pulse risetime, pulse jitter time, gas gain, spectral resolution, neutron sensitivity, and gamma ray sensitivity.
