Test your devices with the brightest steady-state neutron fusion source in the world.
Neutrons at 14 MeV produce unique conditions ideal for evaluating microelectronics. Proving survival under that stress marks a critical benchmark for rad-hard defense and aerospace components.
FLARE delivers that capability, outpacing legacy facilities with the highest steady-state 14 MeV neutron flux in the industry. It produces up to 50 trillion fusions per second, more than 20× the intensity of older accelerators.
And because we operate FLARE as a dedicated service, your team can count on reliable beam time—delivering results in hours or days, not months.

FLARE breaks through the limits of legacy test facilities. How? By combining fusion technology with a facility built for steady, predictable operations.
Our spacious irradiation chamber supports multiple parts at once under varying conditions, accelerating qualification while reducing costs.
Test on your schedule with FLARE.
“There's no better facility than FLARE for 14 MeV neutrons. We'll be using FLARE. Full stop.”
— Major defense prime contractor
FLARE is as powerful as it is practical, designed for maximum throughput and speed. Qualify your mission-critical components with repeatable precision and the fidelity of a true 14 MeV spectrum.
Recent upgrades support faster turnaround, flexible test configurations, real-time monitoring, and a more secure infrastructure.
High throughput. Dual 16″×16″×8″ rapid-loading frames enable parallel irradiation.
Proven methods. Supports industry-standard SEE and Displacement Damage testing.
Fast cycles. Steady-state runs can span from brief bursts to multi-day sessions (10 hours/day), so teams can reach required doses faster.
Validated results. Real-time flux monitoring with foil validation (Ni, In, Au, Nb) ensures auditable, high-fidelity data.
Compliant and secure. ITAR-controlled; ISO 9001/AS9100 aligned.
More than a neutron source, FLARE is a purpose-built environment where test teams can work efficiently, safely, and confidently. Every detail of the facility is engineered to simplify logistics, shorten setup, and deliver reliable results.
Already trusted by leading aerospace and defense teams, FLARE provides the assurance of a proven partner.
Dedicated facility. Lab licensed for tritium operations on our secure campus in Janesville, Wisconsin.
No EMI in the neutron field. Sensitive electronics perform without interference.
Short cable runs. Dedicated customer space next to the irradiation area supports reliable monitoring and data capture.
Flexible access. Source reachable from two sides; dual rapid-loading frames enable simultaneous or serialized test runs.
Integrated support. Watertight ducts for power/communications; backed by licensed accelerator operators, tritium handlers, and radiation safety professionals.
Compliance assured. ITAR-controlled, ISO 9001/AS9100 aligned, DoD-ready.
Want to know more about FLARE? You’re in good company! Check out these common questions and our responses.
Janesville has plenty to keep you busy while your parts are in the beam. Stroll the Rotary Botanical Gardens, stop by the Rock County Historical Society, or stretch your legs in one of our nearby parks or trails. Car enthusiast? Don’t miss the historic auto attractions. Architecture buff? Head to the Frank Lloyd Wright Visitor Center just up the road. Or make a quick trip north to Madison, Wisconsin’s capital city, for museums, dining, and lakefront views.
The maximum dimensions for parts we can test are 32 inches wide, 11 inches deep, 35 inches tall.
As an approximate line source, the flux is isotropic in the radial direction from the center target, which has an approximate diameter of 6 inches.
We validate with activation foils that are analyzed on site.
You need 50 feet of cable.
While FLARE is ITAR compliant, it does not possess a facility clearance.
Please contact us with your specific needs to ensure compliance with our radioactive materials license.
The return timeline of irradiated components varies based on irradiation time and elemental composition of the items, as well as your facility’s ability to receive and possess activated components. Non-irradiated components are typically shipped back within two weeks of the test. We are also able to ship radioactive material and can facilitate disposal of highly activated components.
The > 10 MeV neutron flux varies from 2E9 to 1E8 n/cm2/s, depending on position within the irradiation cavity. The total neutron flux varies from 5E9 to 5E8 n/cm2/s over the same area.
