“It’s a big software engineering task to develop a platform that works at multiple facilities, where there are different constraints and different instruments,” said Thorsten Hellert, an ATAP staff scientist and part of the Accelerator Physics Program at the Advanced Light Source (ALS), where Osprey was first deployed.

Osprey is designed to improve accelerator performance and will be an important part of the upgraded ALS.

The SYNAPS-I project is changing how users do science at the light sources across the country. This time, see how the work is happening st Center for Nanoscale Materials’ hard X-ray nanoprobe beamline at the Advanced Photon Source.

Science Friday! Check out this new video on the SYNAPS-I project and Argonne's role in it. SYNAPS-I is part of the @.S. Department of U.S. Department of Energy's Genesis Mission.

The SYNAPS-I team is led by Berkeley Lab and includes Argonne National Laboratory, Brookhaven National Laboratory, SLAC National Accelerator Laboratory and Oak Ridge National Laboratory. Partner facilities include the Advanced Light Source, Argonne Leadership Computing Facility, High Flux Isotope Reactor, Linac Coherent Light Source (LCLS), National Energy Research Scientific Computing Center (NERSC), National Synchrotron Light Source II (NSLS-II), Spallation Neutron Source and Stanford Synchrotron Radiation Lightsource. Tests were performed at the Center for Nanoscale Materials beamline at the APS.

The SYnergistic Neutron and Photon Science – Intelligence (SYNAPS-I) project is accelerating discovery, thanks to expertise and hard work from computer scientists, beamline scientists, and experimentalists. This embodies , and we love what our teammates at Argonne National Laboratory's Advanced Photon Source are doing with ptychography for the microelectronics field.

Take a look at their latest SYNAPS-I news!

AI is moving beyond analyzing scientific data to helping scientists decide what to do next. At a recent demonstration at Argonne, the SYNAPS-I project (part of the U.S. Department of Energy's Genesis Mission) unveiled agentic AI that can understand natural-language instructions, analyze X-ray images in real time, find important features and autonomously guide experiments.

The work points toward a future of “self-driving” scientific instruments, where AI can adapt experiments as they happen and help researchers explore materials faster and more efficiently.

The SYNAPS-I team is led by Berkeley Lab and includes Argonne National Laboratory, Brookhaven National Laboratory, SLAC National Accelerator Laboratory and Oak Ridge National Laboratory. Partner facilities include the Advanced Light Source, Argonne Leadership Computing Facility, High Flux Isotope Reactor, Linac Coherent Light Source, National Energy Research Scientific Computing Center, National Synchrotron Light Source II, Spallation Neutron Source and Stanford Synchrotron Radiation Light Source. Tests were performed at the Center for Nanoscale Materials beamline at the APS.

As the devices in our pockets and on our desks are expected to do more every year, the microchips inside them need to be more advanced, too. Researchers like Thomas Ferron and Qi Zhang are using beamline 11.0.1.2 at the Advanced Light Source, where resonant soft X-ray scattering can reveal buried nanostructures in polymers and other organic materials used in extreme UV photolithography. With this information, we provide the crucial ingredients to develop the microchips of the future.

The Advanced Light Source (ALS) has been working with NASA - National Aeronautics and Space Administration for over a decade to study a crucial, life-saving process: how spacecraft heat shields degrade under extreme conditions during atmospheric reentry.

This time, researchers reached even higher temperatures than ever before — using a custom sample environment found only at the ALS that independently controls temperature, pressure, and gas mixture to recreate real reentry conditions.

Using X-ray micro-computed tomography combined with AI-powered image enhancement, the team captured real-time, 3D views of two NASA heat shield materials as they broke down at 1,652°F — revealing striking structural differences that affect how each performs during reentry.

"Nearly every major NASA ablative heat shield material has been studied with this technique at the Advanced Light Source, including those relevant to the Artemis and Mars entry missions," said Vishnu Oruganti, an ALS user.

The findings are already helping engineers improve how they model and design thermal protection systems for missions like Artemis — bringing crews home safely.
