Bespoke detector solutions and associated electronics, engineered for your exact specifications.
Industries We Serve
Our radiation detectors operate in some of the most demanding environments on Earth — and beyond.
X-Ray Fluorescence
High-sensitivity XRF analysis for materials testing, mining, and quality assurance.
Space Instrumentation
Space-grade detector systems built to ESA specifications for satellite and mission-critical instruments.
Nuclear Research
Precision counting for particle physics experiments, nuclear spectroscopy, and radiation studies.
Medical Physics
Dosimetry and radiation monitoring instruments for medical research and radiotherapy applications.
Industrial NDT
Non-destructive testing detectors for quality control in manufacturing and materials inspection.
Environmental Monitoring
Radiation level monitoring systems for environmental protection and regulatory compliance.
Academic Research
Reliable detectors for university physics labs, doctoral research, and academic instrumentation.
Security & Defence
Radiation screening systems for border control, nuclear security, and defence applications.
How We Work
Every custom detector begins with your requirements and ends with a validated instrument — engineered to perform where it matters most.
Define Requirements
We begin with a technical consultation to understand your energy range, environment, form factor, and measurement goals.
Engineering Design
Our engineers design the detector geometry, gas fill configuration, window material, and complete electronics chain.
Prototype & Validate
A working prototype is built and rigorously tested against your specifications before any commitment to production.
Manufacture & Deliver
Final units are produced with full documentation, calibration data, and ongoing technical support.
Developed for the European Space Agency
Fenno-Aurum engineered a custom X-ray detector in collaboration with ESA, presented at IEEE NSS 2019. Our UV sensor research was also featured at NDIP 2022 — demonstrating our capability at the frontier of detection science.
