Characterization of Nova plasmas using an x-ray spectrometer with temporal and spatial resolution
- Lawrence Livermore National Laboratory, P. O. Box 808, Livermore, California 94551 (United States)
Spectroscopic diagnostics have great potential to obtain high temperature measurements of plasmas created in inertial confinement fusion targets. The plasmas may be over 1 mm in size and therefore, one of the first steps in making better spectroscopic measurements has been to develop a spectrograph which takes advantage of gated technology by coupling a Bragg crystal to a microchannel plate. The crystal disperses the x rays, while slits add the ability to image the plasmas in the perpendicular direction. The characteristics of this diagnostic, TSPEC, are evaluated for laser-produced plasmas. Recent data will be presented from colliding plasmas and large-scale hohlraums which indicate that imaging can greatly enhance the ability to diagnose these plasmas.
