Disruptions From the International Thermonuclear Experimental Reactor Can Now Be Countered 10 Times Faster

[ad_1] When ITER, the international fusion experiment, starts up in 2025, one of the major priorities will be to minimize or mitigate violent disruptions that could seriously damage the massive machine. Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed and successfully simulated a prototype of a new device […]

Astronomy & Astrophysics 101: Electromagnetic Spectrum

[ad_1] The electromagnetic spectrum is a range of frequencies of electromagnetic radiation. From long to short wavelength, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Energy travels through space as electromagnetic (EM) waves, which are made up of oscillating electric and magnetic fields. EM waves do not require […]

How Wave-Particle Interactions Generate Other Plasma Waves in Geospace

[ad_1] Arase satellite uncovers coupling between plasma waves and charged particles in Geospace Scientists unravel a bit more of the mystery underlying how wave-particle interactions generate other plasma waves in Geospace. In a recent study published in Physical Review Letters, researchers from Japan show that high-frequency plasma waves in the Geospace can generate low-frequency plasma […]
