A new monochromatic x-ray imaging diagnostic, designed around a 4 channel matrix-Baez microscope and diffraction crystals, has been developed to capture images of an imploding target in inertial confinement fusion (ICF) experiments. 


A team from Los Alamos National Laboratory and the University of Rochester's Laboratory for Laser Energetics has developed a new gated monochromatic x-ray imaging system for use in the national Inertial

Confinement Fusion (ICF) program. The new system improves on existing technology by maintaining temporal and spatial resolution while observing a narrow band of x-rays. This allows researchers to isolate line emission from a single element and reject continuum or background radiation. The imaging system consists of:

  • A grazing incidence KB microscope that forms four images.
  • Four Bragg crystals that make the light from the KB microscope monochromatic.
  • Two computer-controlled rotary stages that rotate the Bragg crystals.
  • A dual microchannel plate (MCP) module that gates or shutters the x-rays.

The new imaging system was tested at both LANL's Trident laser facility and LLE's Omega Upgrade. Researchers believe the system will be an important diagnostic tool for Omega, yielding critical information concerning target symmetry, size, and density of ICF implosions.
