Streak cameras capture x-ray laser emissions
- Los Alamos National Lab., NM (USA). Physics Div.
The soft x-ray streak camera is a versatile tool for exploring the challenging spectrum of x-ray emissions from the UV through the XUV up to tens of kilovolts in x-ray photon energy. When coupled with an appropriate spectrometer or x-ray imaging optic, the streak camera can provide time-resolved spectral or spatial images with a resolution limit of a few picoseconds. The author discusses soft x-ray streak cameras have many applications. In laser-fusion studies, they probe the hot, high-density regions of the fusion implosions and provide information on the compression and re-expansion of the pellet under the intense pressure of the plasma blow-off. These instruments have allowed to probe the supercritical region of laser plasmas to measure the temperature of the target and the energy flow in the laser deposition region with temporal resolution of tens of picoseconds. They have also been used to explore x-ray laser operation in various experiments.
