Licensing Opportunity: Autonomous Ion Mass Spectrometer Sentry (AIMSS) Technology from Los Alamos National Laboratory

This notice from Los Alamos National Laboratory (LANL), managed by Triad National Security, LLC for the Department of Energy (DOE), announces a technology licensing opportunity for the Autonomous Ion Mass Spectrometer Sentry (AIMSS): - AIMSS is a high-resolution, flight-qualified ion mass spectrometer developed in-house at LANL - Capable of distinguishing closely spaced ion species (e.g., N+ and O+) - Applications include space weather monitoring, space domain awareness, and spacecraft operations - The technology is protected by U.S. Patent No. 12,476,101 and other pending patents - LANL is seeking to license AIMSS to existing or start-up companies - Both exclusive and non-exclusive licensing agreements are available - This is not a procurement or solicitation for products or services - No external development, manufacturing, or service contracts are being sought - No specific OEMs or commercial vendors are named, as the technology is developed internally - Interested parties should contact LANL for licensing discussions

Description

Satellite measurements of plasma density and temperature help predict the intensity of geomagnetic storms, which can impact satellites, communications, and power systems. Accurate forecasting requires knowledge of plasma composition. However, typical orbital mass spectrometers have difficulty distinguishing between nitrogen (N+) and oxygen (O+) ions due to their similar masses. This limitation makes it difficult to validate modern space weather models, which depend on accurate knowledge of ion composition in near-Earth space. N+ and O+ ions behave differently in space due to differences in their origin, transport, and loss mechanisms. Improving our ability to distinguish between these ions is critical for understanding and predicting space weather.

Advantages

High mass resolution enables distinction between ion species that are typically unresolved in space-based measurements (e.g., N+ vs O+) Simultaneous measurement of multiple ion species for improved data collection efficiency Commandable ion throughput allows for high dynamic range without detector saturation Flight-qualified design with near-term on-orbit demonstration on the ISS

Technology Description

The AIMSS instrument uses electric and magnetic fields to sort ions first by energy and then by mass. As ions move through the instrument, different species are separated and spread out across the detector as a spectrum, similar to how a prism separates white light into different colors.

First, incoming ions pass through two electrostatic energy filters (ESAs) located at the front of the sensor. These filters allow only ions within a selected energy range to continue through the instrument. By adjusting the voltage applied to each filter, AIMSS can control how many ions reach the detector and adapt to changing plasma density.

Next, the ions enter a magnetic field section that separates them by mass. Lighter ions are deflected more than heavier ions, causing different ion species to land at different positions on the detector.

The detector records where ions land, allowing the instrument to measure multiple ion species at once and determine their mass and energy.

This design achieves clear separation of closely spaced ion species such as N+ and O+, improving the accuracy of plasma composition measurements.

Market Applications

AIMSS supports both scientific and operational markets:

Space Domain Awareness: 
Monitoring plasma density and composition to attribute spacecraft anomalies and charging events. Space Weather Monitoring and Forecasting
: Ion composition measurements of ionospheric plasma to inform space weather models and improve forecasting. Space Station Operations for Lunar and Mars Missions
: Monitoring spacecraft health, contamination, and charging during extravehicular activities (EVAs) and docking operations. Department of Defense / Space Force
: Compliance with requirements for onboard space environment sensors.
