Laser Method Would Heat Fusion Materials Faster

Facebook X LinkedIn Email
Directly targeting ions with lasers could heat certain materials to 1 KeV — equivalent to more than 10 million °F — in 20 fs, or 100 times faster than previously demonstrated. The method, proposed by researchers from Imperial College London, could advance the study of thermonuclear fusion, which seeks to replicate the sun's ability to produce energy. Other potential applications include proton imaging, cancer therapies and materials science. When lasers are used to heat most materials, ions, which make up the bulk of matter, are only indirectly heated via electrons...Read full article

    fusion
    1. The combination of the effects of two or more stimuli in any given sense to form a single sensation. With respect to vision, the perception of continuous illumination formed by the rapid successive presentation of light flashes at a specified rate. 2. The transition of matter from solid to liquid form. 3. With respect to atomic or nuclear fusion, the combination of atomic nuclei, under extreme heat, to form a heavier nucleus.
