Scientists Propose New Model of the Source of a Mysterious Barrier to Fusion Known as the “Density Limit”

Davegates.jpeg

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a detailed model of the source of a puzzling limitation on fusion reactions. The findings, published this month in Physics of Plasmas, complete and confirm previous PPPL research and could lead to steps to overcome the barrier if the model proves consistent with experimental data.

Using Muons from Cosmic Rays to Find Fraying Infrastructure

ADV-Durham-muon.jpg

Seeking a better way to identify faulty energy infrastructure before it fails, researchers at Los Alamos National Laboratory are using subatomic particles called muons to analyze the thickness of concrete slabs and metal pipes. Their technique, described in a June 30 paper in the journal AIP Advances, from AIP Publishing, is a way to safely and non-invasively find worn infrastructure components using background radiation already present in the environment.

Researchers from the University of Wisconsin-Madison have come up with a new solution to alleviate the environmental burden of discarded electronics. They have demonstrated the feasibility of making microwave biodegradable thin-film transistors from a transparent, flexible biodegradable substrate made from inexpensive wood, called cellulose nanofibrillated fiber (CNF). This work opens the door for green, low-cost, portable electronic devices in future.

Coil for the Next Upgrade of the Large Hadron Collider Passes Tests

LARP.jpg

Last month, a group collaborating across four national laboratories completed the first successful tests of a superconducting coil in preparation for the future high-luminosity upgrade of the Large Hadron Collider, or HL-LHC. These tests indicate that the magnet design may be adequate for its intended use.

X Marks the Spot: Researchers Confirm Novel Method for Controlling Plasma Rotation to Improve Fusion Performance

Rotation_Image_1.jpg

Timothy Stoltzfus-Dueck, a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), has demonstrated a novel method that scientists can use to manipulate the intrinsic – or self-generated – rotation of hot, charged plasma gas within fusion facilities called tokamaks.
