The system
A complete AtOx facility — in your lab.
Source, vacuum stack and control cabinet on a compact skid — delivered, installed and calibrated. Or supplied as a standalone source to retrofit onto your existing vacuum chamber.
This is the best atomic-oxygen source on the market — and you can own it. Hyperthermal, fully tunable, and so fast that ~4 hours of exposure equals a year in orbit. Test more, wait less, and get flight-relevant answers while your competitors are still queuing for a facility.
No other atomic-oxygen source combines true LEO energy, remote tunability and non-stop uptime — and lets you buy it outright.
Set the exposure remotely by discharge voltage and frequency — repeatable, LEO-representative conditions every single run. Match a specific orbit, not a fixed recipe.
No heated filament, no fast-wearing parts, no technology breaks — full output campaign after campaign. ~4 hours of exposure ≈ one year of LEO dose, ready whenever you need it.
Buy the source or the whole system instead of renting time in someone else's facility. Designed, built and supported in Europe — fast delivery, fast answers.

Whether you need one answer fast or your own testing capability for years, there's a route that fits. Tell us which and we'll price it in days.
Need an answer now, without buying hardware? Send us your samples and we'll hand you flight-relevant erosion data your programme can act on.
Already have a vacuum chamber? Add AtOx capability to it for a fraction of a full facility — and stop paying for outside test time.
Make LEO testing your own capability: a complete system built to your spec, commissioned in your building, earning its keep from the first campaign.

Our plasma technology underpins atomic-oxygen apparatus used in real research — from national-defence labs to INFN spin-offs.
“Noivion's plasma technology formed the basis for the design and realization of Atomic-Oxygen testing apparatus… essential in enabling reliable and repeatable exposure conditions for high-level experimental campaigns in aerospace and materials science.”

AtOx testing alongside RHA and TVAC per ESA standards.
Signed reference letter for the AtOx development.
AtOx generates atomic oxygen by a pulsed-electron pseudo-spark discharge that ionises the gas essentially completely in every pulse — the mechanism behind its energy, its tunability and its uptime.
Full ionisation, every pulse. A discharge of up to 25 kV lasting under 1 µs ionises the oxygen flowing through a De Laval nozzle, producing a directed, high-energy atomic-oxygen beam — not a weak thermal glow.
Energy that matches orbit. The beam reaches 1–5 eV at 4–8 km/s — the same hyperthermal impact satellites face in LEO. Flux and energy are set remotely by voltage and frequency, so one source covers many orbits and test standards.
Nothing to burn out. There is no heated filament and no fast-wearing part in the discharge path — the reason it sustains full output campaign after campaign, and why ~4 hours of exposure can stand in for a year in orbit.
Verified, not assumed. Every exposure is calibrated against Kapton HN witness samples (ASTM E2089), and the plasma itself is independently characterised — optical emission at 777 nm plus energy and mass distribution of oxygen isotopes.
Flux is calibrated against Kapton HN witness samples per ASTM E2089 — mass loss measured on a 1 µg microbalance after full vacuum dehydration.
