Fusion Diagnostics
Diagnostics for next-gen MCF devices and future FPPs — from physics-based design to manufacturing and lifetime support — delivered as standalone systems or as part of our Modular Diagnostics Platform.
A new fusion device has to decide what to measure long before it is built — for physics validation, plasma control, device safety, and the licensing case — yet early-stage companies usually don't yet know these needs. Commercial fusion adds its own demand: diagnostics that work in a high-energy neutron environment, operate 24/7 as commercial devices do, and are standardized, off-the-shelf, and fast-replaceable.
From day one, we support builders of tokamaks, stellarators, and other MCF devices with diagnostics based on world-class science, backed by tools for their design, engineering, and optimization, and provided as industrial solutions with lifetime support.
Read on to see what we offer, or get in touch to talk about your device.
What We Offer
Diagnostics feasibility study
We start from the measurements: what must be measured on your device, and why, and which diagnostics are applicable to your device and parameters. Engaging early lets us design diagnostics for cost efficiency, operational simplicity, and a smaller diagnostics footprint on the device, feed port and access needs back into the device design, and build plasma control and device safety in from the start.
Modular Diagnostics Platform (MDP)
Every diagnostic we develop is available standalone — or as part of the MDP, our integrated solution: a unified, standardized set of plasma diagnostics, minimalistic yet sufficient for stable control of a fusion plant. It combines hot-swappable port-plug units for the diagnostics that suit them, data acquisition (VIDA), real-time plasma state reconstruction, and a supply chain built on standardized, fast-replaceable components.
Microwave diagnostics
Non-perturbative, with no in-vessel calibration targets, and reliable in high magnetic field and neutron environments. Our on-chip ECE radiometer delivers localized, absolute electron temperature profiles in real time; our multi-band, dual-polarization profile reflectometer measures electron density profiles from small-aperture antennas with no large ports or beam lines. Both share a single port plug.
Magnetic diagnostics
THOR: a graphene-on-silicon-carbide Hall sensor measuring absolute magnetic field instantaneously — no time integration, no drift over long pulses. It offers ~75 V/AT sensitivity (75–80× above metal Hall sensors), stable operation to 770 K, self-healing of neutron damage through thermal annealing, and a 1.4 mm × 1.4 mm footprint. Now maturing from TRL 4 to TRL 6.
Neutron diagnostics
A miniature, fully passive graphene-on-SiC dosimeter for spatially resolved fast-neutron fluence measurement — no power or cabling during exposure, read out non-destructively by Raman spectroscopy afterward. Demonstrated up to 6.5×1018 n/cm2, with a built-in reference region for self-verified fluence estimation, for reactor qualification and component lifetime assessment.
More diagnostics, designed from physics
We are doing much more than microwave, magnetic, and neutron diagnostics: we are extending to the other measurement systems next-gen MCF devices and FPPs need. For each, we start with physics models, synthetic diagnostics, and design tools that simulate the expected signals for your device and scenarios, so sightlines, sensor placement, and measurement ranges are optimized before any hardware is built — and we deliver an optimized solution.
