Industry Applications

Featured Solutions

UV Flame Detectors

UV Flame Detectors

uv flame detectors

Reuter-Stokes is well-known in the industry for its reliable Flame Tracker family of flame sensors. Both the UV-based Flame Tracker and the Flame Tracker Dry FTD325 are standard OEM and help reduce maintenance costs while removing the risk of damage from complex water-cooling systems by safeguarding temperature-sensitive components.

3He Neutron Detectors

3He Neutron Detectors

he-3 detectors

Our Helium-3 (3He)-filled neutron detectors are designed to offer the optimal combination of high efficiency and sensitivity, with excellent gamma discrimination and vibration response - all in the most compact package possible. 

Gamma-Ray Scintillation Detectors

Gamma-Ray Scintillation Detectors

Reuter-Stokes tailors every scintillation detector to your exact specifications.

We provide a broad range of detector configurations, including virtually any crystal size, mounting, and interface adaptations, as well as built-in radioactive check sources.

Using the highest quality materials and cutting-edge design, Reuter-Stokes is committed to engineering its sensors to meet strict customer specifications.

Boron 10 Neutron Detectors

Boron 10 Neutron Detectors

The Boron-10 Neutron Detectors are ideal for neutron detection in mixed neutron and gamma fields. With the proper electronics and discriminator settings, these detectors operate at gamma dose rates up to 103 R/hr with an approximate 50% reduction in neutron sensitivity. 

Applications ideal for this type of detector include spent nuclear fuel measurements in safeguards and start-up neutron detectors for nuclear research reactors.

Ex-Core Detectors

Ex-Core Detectors

Reuter-Stokes, a Baker Hughes business, provides critical components to the Nuclear Instrumentation System (NIS) for source (SR), intermediate (IR) and power range (PR) neutron detectors, including guarded (WG) and unguarded (WU) wide-range detectors.

Reuter-Stokes also offers additional components to support Pressurized Water Reactors (PWR) and Boiling Water Reactors (BWR) including environmental monitoring of:

  • ion chambers
  • gamma thermometer LPRM probes
  • dry tube assemblies
  • position indicators
  • water chemistry probes


Directional Sensors & Orientation Modules

Orientation Modules

Reuter-Stokes’ orientation modules are designed for efficient operation in a compact, rugged chassis

By providing accurate and stable survey measurements, with minimal downhole power consumption, the module has helped customers lower operational costs associated with downhole batteries and enabled the horizontal drilling techniques required for unconventional resource development.

Combining robust packaging with high-temperature electronics, our orientation modules are calibrated to deliver accurate survey data over a wide operating temperature range from -20˚C to 175˚C (-4˚F to 347˚F), with downhole vibration up to 20 grms.

Position-Sensitive Proportional Counters

Position-Sensitive Proportional Counters

Reuter-Stokes offers 3He filled position-sensitive proportional counters, otherwise known as Position Sensitive Detectors or PSDs, and standard 3He detectors for the neutron scattering industry.

These Reuter-Stokes detectors, used in neutron scattering facilities throughout the world, have become the industry’s benchmark detectors, providing scalable solutions for every instrument from SANS to Time-of-Flight.

Data Acquisition Systems for Spectroscopy

Data Acquisition Systems

Reuter-Stokes' NeuAcq* Electronics System, the next-generation data acquisition electronics system for neutron scattering, provides superior speed and accuracy for time-stamping and processing neutron events. 

NeuAcq* is a Linux and Ethernet-based system with Precision Time Protocol (PTP), Power over Ethernet (POE), and standard TCP/IP network communications. 

ADARA compliant, NeuAcq* supports EPICS control systems and is compatible with Mantid visualization and data processing software.
