DELERA is designed to accompany the Gamma-Ray Energy Tracking Array (GRETA), a next-generation nuclear spectrometer currently under construction at Berkeley Lab. GRETA represents a leap forward in detector technology, encompassing a spherical assembly of 120 hyper-pure germanium crystals arranged to capture detailed data during nuclear reaction events. Scheduled for installation at the Facility for Rare Isotope Beams (FRIB), Michigan State University, in 2026, GRETA will investigate atomic nuclei by detecting the gamma rays released when samples are bombarded with charged particles accelerated within FRIB’s radioactive ion accelerator. This innovative combination of experimental hardware and software promises to unravel complex nuclear structures with unprecedented precision.

The software backbone supporting GRETA’s mission, DELERIA, enables the system to stream raw experimental data directly to some of the nation’s most powerful supercomputing facilities. By leveraging the Energy Sciences Network (ESnet), a DOE-supported infrastructure for high-speed data transport, DELERIA transmits experimental information from Berkeley Lab to Oak Ridge Leadership Computing Facility (OLCF) processors nearly 2,000 miles away. This direct pipeline allows the massive dataset from photon collision events to be processed instantaneously within sophisticated computing clusters, eliminating the need for costly and bulky local computing setups. The result? Scientists receive real-time feedback that can inform experimental settings dynamically, increasing the expedition and accuracy of nuclear research.

GRETA’s design hinges on its array of ultra-pure germanium detectors, each capable of recording the energy and positional coordinates of incoming gamma photons emitted during nuclear reactions. When the radioactive ion beam collides with atomic samples, the resultant nuclear transitions generate an intense flux of photons—on the order of hundreds of thousands per second—that strike the detectors. Each interaction generates electrical signals transmitted through multiple contact points on the crystals. Computing these signal patterns to determine the three-dimensional coordinates (X, Y, Z) and energies of photons requires immense computational throughput.

Here, DELERIA’s intricate data pipeline shines. The computational workload involves transforming complex raw data from the individual crystal contacts into meaningful spatial and energetic information about each photon event. This is performed under stringent latency constraints: each interaction must be analyzed and recorded within 10 seconds to maintain real-time feedback. The ORNL team, utilizing OLCF’s Defiant cluster—an AMD GPU-accelerated system consisting of 36 nodes—provides the necessary parallel processing power to tackle these calculations. By offloading data analysis to national computing centers, DELERIA drastically reduces GRETA’s local infrastructure demands, offering a scalable and flexible solution that can adapt to future upgrades or extensions to other experimental facilities.

A key innovation of DELERIA lies in its remarkable data compression capabilities. By intelligently filtering and interpreting collision events, the software reduces data storage needs by a factor of 40, achieving a 97.5% reduction in data volume without compromising informational fidelity. This compression allows scientists to preserve critical data for prolonged analysis or archival purposes without overwhelming storage systems. Simultaneously, the system maintains the high granularity needed for detailed nuclear modeling and interpretation.

To validate the feasibility of this ambitious pipeline, the research team constructed a virtual testbed simulating GRETA’s detector array at Berkeley Lab. This simulation generates synthetic photon collision events that mimic real experimental conditions and sends their data streams via ESnet over 4,000 miles round-trip to the OLCF computing cluster for processing. The system currently handles approximately 480,000 photon events per second, processing and returning analyzed data to Berkeley in under 10 seconds—demonstrating the capacity for true real-time nuclear event analysis across continental distances.

Despite this success, the team faces formidable challenges associated with data latency over long-distance transmission. While the computational processing time for a single photon event is an impressively low 5 milliseconds, the light-speed-limited data transmission between Berkeley Lab and OLCF takes approximately 120 milliseconds round-trip. This disparity highlights inherent physics-imposed limits that cannot be bypassed, necessitating novel computational strategies to maintain efficient throughput.

To overcome latency bottlenecks, researchers have devised a method of parallel event processing capable of “tricking” the delay caused by data travel time. By concurrently analyzing multiple photon events in a pipeline fashion, where some events are being processed while others are still in transmission, the system keeps computing resources fully occupied. This concurrency-driven approach ultimately accelerates overall analysis timelines by roughly an order of magnitude, ensuring the supercomputer cluster remains busy and avoids idle wait times during transmission delays.

This DELERIA-powered infrastructure is part of a broader vision materializing under the Advanced Computing Ecosystem (ACE) program at OLCF. ACE serves as a testbed infrastructure providing experimental capability across a spectrum of computing architectures, fully integrating DOE’s leadership-class computational centers with national scientific facilities under the Integrated Research Infrastructure (IRI) initiative. By aligning high-performance computing assets, cutting-edge networking, and user-driven research, ACE targets transformative scientific capabilities across disciplines—from nuclear physics to materials science and beyond.

This pioneering collaboration not only pioneers handling extreme-scale nuclear data streams but also sets the stage for scaling similar data pipelines across diverse DOE research platforms. Among the core team leading this endeavor are Gustav Jansen from ORNL, Mario Cromaz from Berkeley Lab, and experts across the ESnet and OLCF teams. Their collective expertise demonstrates a successful proof of concept for streaming and processing big data in real-time—an imperative advancement as experimental science delves into increasingly complex phenomena demanding rapid analytic turnaround.

In the long term, DELERIA and GRETA’s synergy could significantly expand the frontiers of nuclear physics, allowing scientists to investigate fine-grained nuclear structure and reaction dynamics faster and more reliably than ever before. This capability is essential for answering fundamental questions about atomic nuclei and their behavior, which has implications ranging from nuclear energy to astrophysics. As the GRETA spectrometer comes online and DELERIA matures, the scientific community anticipates a new era where data is more than just collected—it is immediately harnessed, understood, and applied.

Ultimately, the successful deployment of DELERIA stands as a testament to how combining innovative software design, powerful supercomputing resources, and ultra-high-speed networking infrastructure can transform scientific discovery. By pushing the boundaries of data processing speed and efficiency, this project not only accelerates nuclear research but also lays down scalable frameworks for future scientific Big Data challenges across disciplines and national laboratories.

Sarbajit Banerjee, the senior author and a leading chemist, explained that the team’s innovation is a significant stride towards eliminating a longstanding impasse in the pursuit of nuclear energy and making lithium-6 more accessible for various applications. He notes that this methodological advancement could be a game-changer for the future of nuclear fusion, a clean energy source long sought by scientists and energy policymakers alike. As the world races for sustainable energy solutions, the implications of improved access to lithium-6 could resonate far beyond nuclear applications.

The innovative technique that allows for lithium-6 enrichment emerged serendipitously while the team was exploring methodologies for purifying “produced water,” which refers to the contaminated groundwater that surfaces during oil and gas extraction. During their investigations, researchers discovered that their newly developed membranes were exceptionally selective at capturing lithium from the compromised water. This unexpected finding ignited their curiosity about the potential of these membranes to isolate lithium-6 from the more abundant lithium-7 isotopes present.

Central to the newfound method is a material known as zeta-vanadium oxide (ζ-V₂O₅), which is an inorganic compound engineered in the laboratory. This sophisticated compound showcases unique properties enabling it to attract lithium ions selectively due to its one-dimensional tunnel-like structural framework. Banerjee highlights that the zeta-V₂O₅ material’s remarkable characteristics not only lend themselves to energy storage applications, making it a phenomenal battery component, but also enhance its efficacy in isotope separation.

In a laboratory setup designed to evaluate the separation process, the research team constructed an electrochemical cell utilizing a zeta-V₂O₅ cathode. Upon introducing an aqueous solution containing lithium ions while applying electrical voltage, the cations migrated toward the negatively charged zeta-V₂O₅ matrix, penetrating into its intricate tunnels. The intrinsic differences in movement between lithium isotopes, due to their distinct masses, allow zeta-V₂O₅ to preferentially retain lithium-6 ions effectively.

The experimental results illustrate that lithium-6 ions adhere more robustly to the zeta-V₂O₅ tunnels compared to lithium-7 ions. As co-first author Andrew Ezazi explained, an analogy can be drawn using the tension of a spring—the lighter lithium-6 resonates in harmony with the bonds formed with vanadium oxide, while heavier lithium-7 is more prone to disrupt this connection, thus facilitating the absorption process. This nuanced mechanism of selectivity underscores the innovative shift away from toxic isolation methods.

As the process unfolds, an intriguing visual transformation occurs with the zeta-V₂O₅ compound—its color transitions from vibrant yellow to a dark olive green. This dramatic color change not only serves as an aesthetic marker of the lithium isolation process but also provides an essential visual cue for researchers monitoring the degree of lithium-6 enrichment over successive cycles, adding a layer of practicality to the method.

In their findings, the team reported that a single electrochemical cycle successfully enriched lithium-6 concentrations by approximately 5.7%. However, in order to obtain fusion-grade lithium—which necessitates a minimum of 30% lithium-6—the procedure requires repetition, with about 25 cycles needed for effective extraction. Interestingly, researchers projected that it may be possible to achieve an impressive 90% lithium-6 purity after roughly 45 cycles, showcasing a practical roadmap for escalating the efficiency of lithium separation processes.

While this discovery represents significant progress, Banerjee noted that current efforts do not yet extend to industrial-scale production of lithium-6. There remain substantial engineering challenges to negotiate, particularly in terms of optimizing the design of continuous flow systems that would facilitate the economical large-scale production of lithium-6 from seawater or contaminated sources. Nevertheless, preliminary results paint a promising picture, highlighting the potential for this technology to provide a low-cost source of fusion-grade lithium in the near future.

Additionally, the research team speculates that the principles governing the zeta-V₂O₅ material’s selective extraction capabilities could be extended to separate other isotopes—including those that are radioactive—from their non-radioactive counterparts. This broader scope of application reinforces the potential impact of their findings on various scientific fields, paving the way toward an array of innovative techniques for material separation.

As researchers prepare for the next steps, their focus shifts towards scaling the process for commercial viability. Banerjee expressed optimism regarding the future of nuclear fusion, suggesting that with the right support and collaboration, their findings could usher in a new era of clean energy production, unlocking the full potential of nuclear technology. The global interest in fusion energy has surged, propelling this research to prominence as the scientific community looks to translate findings into actionable solutions to environmental and energy crises.

In conclusion, the work conducted by Banerjee and his team stands as a testament to the powerful intersection of innovative material science and environmental sustainability. By challenging conventions and reimagining traditional processes, they have unlocked a method that could significantly influence the landscape of nuclear fusion and isotopic enrichment, all while sidestepping the health hazards associated with toxic materials. The pathway forward is laden with promise, and as excitement builds, the world watches and hopes for breakthroughs that could ultimately alter the very fabric of energy generation.
