  • Microwave pulse compression in dispersive plasmas
    Patent number: 4758795
    Abstract: A plasma-filled waveguide acts as a dispersive element for pulse compression or power multiplication of a frequency chirped microwave signal. In one embodiment, the frequency of the source is chirped near a plasma resonance while the plasma waveguide is held contant in time. In a second embodiment, the source frequency is held fixed while the plasma filled waveguide parameters are varied in time in the vicinity of a plasma resonance.

  • Radiative opacity and emissivity measuring device
    Patent number: 4597933
    Abstract: An apparatus for measuring the emissivity and opacity coefficients of a test plasma. The apparatus includes a target comprising a support structure of a carrier material with an asymmetrical sample of a test material disposed thereon, a driver for ionizing the test material into a test plasma and the carrier material into a carrier plasma, and spectrographs for measuring the intensity of photons traversing said test plasma. Embodiments including a separate photon source are also disclosed.
