NERSC Resources Help PPPL Team Predict Plasma Pressure in Future Fusion Facilities
Researchers at the Princeton Plasma Physics Laboratory have developed new insights into the physics governing the balance of pressure in the scrape-off layer, the thin strip of gas at the edge of the plasma in a tokamak reactor. Read More »
Hydrogen a Culprit in Capacity Loss of Sodium-Ion Batteries
Using NERSC's Cori system, UC Santa Barbara computational materials scientist Chris Van de Walle and colleagues have uncovered a reason for the loss of capacity that occurs over time in sodium batteries. Read More »
Berkeley Lab Deep Learning Expertise Draws Attention at International Climatology Meeting
Berkeley Lab’s growing expertise in applying machine learning methods to extreme weather event studies led to invitations to present at the 2019 International Meeting on Statistical Climatology, a prestigious event held only every three years. Read More »
Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment
Most of the remaining components needed to fully assemble an underground dark matter-search experiment called LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June. Once it is up and running, data captured by the detectors’ electronics will ultimately be transferred to NERSC, LZ’s primary data center, via ESnet. Read More »
Three Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument
It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.

Cleaning Cosmic Microwave Background Data to Measure Gravitational Lensing
Gravity from distant galaxies cause tiny distortions in cosmic microwave background temperature maps - a process called gravitational lensing - which are detected by data analysis software run on supercomputers like the Cori system at NERSC. Unfortunately, this temperature data is often corrupted by foreground emissions from extragalactic dust, gas, and other noise sources that are challenging to model. So Berkeley Lab researchers developed a statistical method for analyzing CMB data that is largely immune to the foreground noise effects. Read More »
CosmoGAN: Training a Neural Network to Study Dark Matter
A Berkeley Lab-led research group is using a deep learning method known as generative adversarial networks to enhance the use of gravitational lensing in the study of dark matter. Read More »
