Piece summarizes invited PPPL talks ranging from fusion to astrophysics at 60th APS-DPP annual meeting.
Physicists at Johannes Gutenberg University Mainz (JGU) have recently succeeded in observing parity violation in ytterbium atoms with different numbers of neutrons. The research was published in the renowned Nature Physics journal.
Scientists from IOCB Prague and IMC have developed a revolutionary method for the easy and inexpensive production of irradiated nanodiamonds and other nanomaterials suitable for use in highly sensitive diagnostics of diseases, including various types of cancer. Their article was recently published in Nature Communications.
Laser-based 'optical tweezers' could levitate uranium and plutonium particles, thus allowing the measurement of nuclear recoil during radioactive decay. This technique, proposed by scientists at Los Alamos National Laboratory, provides a new method for conducting the radioactive particle analysis essential to nuclear forensics
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 superconductors, which can be used to build magnets that produce stronger magnetic fields than previously possible -- could help them achieve this goal. Researchers plan to use this technology to build magnets at the scale required for fusion
Scientists have produced an extremely bright spot of light that can travel at any speed -- including faster than the speed of light. Researchers have found a way to use this concept, called 'flying focus,' to move an intense laser focal point over long distances at any speed. Their technique includes capturing some of the fastest movies ever recorded.
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 them strong magnetic fields which can interact with or effect other magnetic fields, such as those that surround planets like Earth. To understand these processes, researchers are employing laboratory experiments to study magnetic flows up close.
Fusion offers the potential of near limitless energy by heating a gas trapped in a magnetic field to incredibly high temperatures where atoms are so energetic that they fuse together when they collide. But if that hot gas, called a plasma, breaks free from the magnetic field, it must be safely put back in place to avoid damaging the fusion device -- this problem has been one of the great challenges of magnetically confined fusion.
In a lab on Earth, electrically charged dust generally lines up either along the downward pull of gravity or across it. Scientists at the Center for Astrophysics, Space Physics, and Engineering Research (CASPER), at Baylor University, got a surprise when examining data from a similar experiment on the International Space Station orbiting 248 miles above Earth. Rather than the dust bouncing around randomly, the dust often wiggled around in straight lines, even without gravity.
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 fast moving atomic particles slam into each other and stick together. The particles need to be so hot that atoms break down, leaving a gas of charged particles called a plasma.
