What’s New

San Diego-based General Atomics (GA) has published a new app to help physicists work out the characteristics of plasmas on the fly. Called Plasmatica, it takes up to seven basic input parameters—ranging from magnetic field to electron temperature to ion mass factor—and outputs many fundamental properties of the plasma. The parameters are helpful to researchers because they describe intrinsic plasma behaviors, e.g., how often particles will collide with each other.

"Before this, most of us just would have written a little program on our computers to do these calculations, and in fact a bunch of us have them," said David Pace, the GA physicist who spurred the development of Plasmatica. "We thought it would be nice to give back to the research community by creating a standardized app that everyone can use when they're not at their computers. It's been exciting to get some initial feedback that is guiding us to a new round of improvements."

GA operates the DIII-D National Fusion Facility, the largest magnetic fusion facility operating in the U.S. and a world-renowned research center for plasma physics. Research time on DIII-D is extremely valuable—the facility can accept only about one out of every five experimental proposals—so having those calculations accessible on a mobile device can save precious minutes when researchers are trying to line up the next experiment.

The app, which incorporates two formularies commonly used by plasma physicists, has been tested by researchers and is getting solid reviews. Plasmatica is available for free in both the Android and Apple app stores.

The first Fusion in Europe of 2018 has been released. This quarterly magazine, published by the European consortium EUROfusion, keeps readers abreast of the faces, facilities and feats of the very dynamic fusion research community in Europe.

The latest issue offers articles on the experimental campaign underway at WEST (France), the 3D printing of small tungsten components, and plans for a neutron source oriented to DEMO (the machine after ITER).

Steven Cowley, a theoretical physicist and international authority on fusion energy, has been named director of the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), effective July 1.

Cowley has served as president of Corpus Christi College and professor of physics at the University of Oxford since 2016. From 2008 through 2016, he was chief executive officer of the United Kingdom Atomic Energy Authority (UKAEA) and head of the Culham Centre for Fusion Energy, which includes the Joint European Torus (JET) and Mega Amp Spherical Tokamak (MAST) fusion facilities.

During his tenure at Culham, Cowley expanded and strengthened relations with other fusion programs in Europe and around the world, and served in key advisory roles for the U.K., U.S. and European governments.

As director of PPPL, Cowley will be responsible for managing all aspects of the laboratory, including its performance in science, engineering, operations, project management and strategic planning. He will lead PPPL's scientific and technical programs in fusion energy science and technology, as well as broader investigations in plasma science, and provide leadership to the U.S. and world fusion energy efforts.
