    en.wikipedia.org/wiki/Atomic_absorption_spectroscopy

    Flame atomic absorption spectroscopy instrument A scientist preparing solutions for atomic absorption spectroscopy, reflected in the glass window of the AAS's flame atomizer cover door. Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative measurement of chemical elements. AAS is based on the absorption of ...

    The design effort took place at General Atomics in San Diego, [4] and supporters included Wernher von Braun, [5] who issued a white paper advocating the idea. [ 2 ] [ 6 ] Non-nuclear tests were conducted with models, [ 7 ] but the project was eventually abandoned for several reasons, including the 1963 Partial Test Ban Treaty , [ 8 ] which ...

  6. Atomic spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_spectroscopy

    In atomic absorption spectroscopy, light of a predetermined wavelength is passed through a collection of atoms. If the wavelength of the source light has energy corresponding to the energy difference between two energy levels in the atoms, a portion of the light will be absorbed.

  7. DIII-D (tokamak) - Wikipedia

    en.wikipedia.org/wiki/DIII-D_(tokamak)

    DIII-D is a tokamak that has been operated since the late 1980s by General Atomics (GA) in San Diego, California, for the United States Department of Energy.The DIII-D National Fusion Facility is part of the ongoing effort to achieve magnetically confined fusion.

  8. Spectral line shape - Wikipedia

    en.wikipedia.org/wiki/Spectral_line_shape

    Absorption spectrum of an aqueous solution of potassium permanganate.The spectrum consists of a series of overlapping lines belonging to a vibronic progression. Spectral line shape or spectral line profile describes the form of an electromagnetic spectrum in the vicinity of a spectral line – a region of stronger or weaker intensity in the spectrum.

  9. Los Alamos National Laboratory - Wikipedia

    en.wikipedia.org/wiki/Los_Alamos_National_Laboratory

    During the late-1950s, a number of scientists including Dr. J. Robert "Bob" Beyster left Los Alamos to work for General Atomics (GA) in San Diego. [17] Three major nuclear-related accidents have occurred at LANL. Criticality accidents occurred in August 1945 and May 1946, and a third accident occurred during an annual physical inventory in ...
