The Blob That Ate the Tokamak: Physicists Gain Understanding of How Bubbles at the Edge of Plasmas Can Drain Heat and Reduce Fusion Reaction Efficiency

Churchill.jpg

Scientists at PPPL have completed new simulations that could provide insight into how blobs at the plasma edge behave. The simulations, produced by a code called XGC1 developed by a national team based at PPPL, performed kinetic simulations of two different regions of the plasma edge simultaneously.

UAH Team Part of Co-Detection That Confirms the Origin of Short Gamma-Ray Bursts

Ms. Rachel Hamburg, a master’s student in UAH’s Department of Space Science and Dr. Péter Veres, a postdoctoral fellow at UAH’s CSPAR, both serve as burst advocates for the GBM Team. As a result, they were two of the first to know of the near-simultaneous detection of gamma rays and gravitational waves from a distant pair of merging neutron stars.

University of Arkansas Researchers Extend BKT Physics to Study of Ferroelectrics

Using first-principles-based simulations, researchers found that an overlooked BKT phase sustained by quasicontinuous symmetry emerges between the ferroelectric and paraelectric phases of ferroelectic ultrathin film,

Iowa State Physicists Contribute to Higgs Boson Analysis, Understanding

ATLASHiggsbb.jpg

Iowa State physicists have been part of the search for evidence the Higgs boson, as predicted, most often decays into two bottom quarks. It has been a challenge -- billions of the quarks are produced in the Large Hadron Collider and most aren't tied to the Higgs.

Agostino “Ago” Marinelli first met pioneering accelerator physicist Claudio Pellegrini as an undergraduate student at the University of Rome. It was 2007, a couple of years before the Linac Coherent Light Source (LCLS) came online at SLAC, and people were abuzz about free-electron laser physics.

How X-Rays Pushed Topological Matter R&D Over the Top

Pioneering X-ray experiments at Berkeley Lab's Advanced Light Source (ALS) helped bring to life decades-old theories about exotic topological states of matter, and the ALS continues to play an important role in this flourishing field of research.

Scientists Watch a Molecule Protect Itself From Radiation Damage

Angewandte_Chemie_cover6.jpg

When DNA is hit with ultraviolet light, it can lose excess energy from radiation by ejecting the core of a hydrogen atom — a single proton — to keep other chemical bonds in the system from breaking. To gain insight into this process, researchers used X-ray laser pulses from the Linac Coherent Light Source (LCLS) at the Department of Energy’s SLAC National Accelerator Laboratory to investigate how energy from light transforms a relatively simple molecule, 2-thiopyridone.
