NIF Fires Record-Setting Laser Shot

Facebook X LinkedIn Email
LIVERMORE, Calif., March 22, 2012 — The 192 lasers fired in unison at the National Ignition Facility (NIF) this week delivered a record 1.875 million joules of ultraviolet laser light to its target chamber, exceeding NIF's original design specification and setting the stage for full-power experiments in the coming months, officials said. "For the past 15 years, since NIF groundbreaking in 1997, the scientific community has regarded the 1.8-MJ milestone as a tremendous technical challenge," said NIF Operations Manager Bruno Van Wonterghem. "In 2003, we demonstrated this performance level on a single beam line, and in 2008...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.
    fusion ignition
    Fusion ignition refers to the point in a controlled nuclear fusion reaction where the energy released by the fusion reactions becomes self-sustaining, leading to a continuous release of energy without the need for external heating. Achieving fusion ignition is a critical milestone in the development of practical fusion energy. Key points about fusion ignition: Nuclear fusion: Fusion is a process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of...
