Supercomputers without waste heat

Generally speaking, magnetism and the lossless flow of electrical current ("superconductivity") are competing phenomena that cannot coexist in the same sample. However, for building supercomputers, synergetically combining ...

High-contrast imaging for cancer therapy with protons

Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology—OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating ...

Magnetic materials for motors of the future

According to a statistic from the University of Chicago, 50 percent of U.S. power goes through a motor. Vehicles like cars and planes rely on motors to transform power, as do household appliances like vacuums and refrigerators. ...

Successful second round of experiments with Wendelstein 7-X

During the course of the step-by-step upgrading of Wendelstein 7-X, the plasma vessel was fitted with inner cladding beginning in September of last year. Graphite tiles are now protecting the vessel walls. In addition, the ...

Taming plasmas: Improving fusion using microwaves

We all know microwaves are good for cooking popcorn, but scientists have recently shown they can also prevent dangerous waves in plasmas and help produce clean, nearly limitless energy with fusion. Fusion takes place when ...

A faster, cheaper path to fusion energy

Scientists are working to dramatically speed up the development of fusion energy in an effort to deliver power to the electric grid soon enough to help mitigate impacts of climate change. The arrival of a breakthrough technology—high-temperature ...

A stellar achievement: Magnetized space winds in the laboratory

New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with ...
