The year 2021 opened a new era in scientific exploration for the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The Laboratory fully expanded from fusion energy research into the science of cost-effective and plasma-enhanced fabrication of materials such as quantum computer chips, the next generation of diamond sensors and a broad array of industrial applications. To help with this process, PPPL is advancing its capabilities into the next generation of supercomputing and has launched a department of high-performance computational science. The following baker’s dozen assortment of stories, in no particular order, exemplifies PPPL’s findings over the past year, ranging from improved ways to harness fusion energy on Earth to new methods for bringing space plasma into the Lab, and using computational analysis and microelectronic exploration to make new discoveries. You can find these, and other stories, at
