Newswise — Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches passing over a periodic grating. In theory, ultra-narrow spectral linewidth of S-SPR could be realized, which would be greatly beneficial to various applications such as imaging, sensing, communication, and et al. However, in the free…
BYLINE: Lauren Biron Newswise — The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its accelerating expansion. New results from the Dark Energy Spectroscopic Instrument (DESI) collaboration use the largest 3D map of our universe ever made to track dark energy’s influence over the past…
Newswise — A group of South Korean researchers has developed a floating point accelerator chip, which is a core technology for supercomputers. Developed for the first time domestically, the accelerator chip plays a crucial role to speed up the calculations of supercomputers. After its commercialization, this technology will be a game-changer for Korea to become…
Newswise — NEWPORT NEWS, VA – The latest addition to the computational arsenal of the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility is an extraordinary machine with the admittedly ordinary name of “24s.” In a world where the fastest of supercomputers have such names as Frontier, Aurora, El Capitan, Jupiter, Blueback, JEDI and…
