Twin-elliptical-crystal time- and space-resolved soft x-ray spectrometer
- Sandia National Laboratories, Albuquerque, New Mexico 87185-1196 (United States)
Elliptical crystal spectrometers equipped with time-gated microchannel plate (MCP) detectors provide time-, space-, and spectrally resolved data. A common problem is that the number of time resolution elements is limited by the number of MCP frames. The number of frames that fit on a given MCP is limited by the image size and the alignment tolerance. At the Z facility these problems have been addressed with twin-elliptical-crystal spectrometers. Using two crystals and detectors doubles the number of frames available. This enables measurements with {approx}350 ps time resolution while still recording data from an {approx}4 ns wide time window. Alternatively, the twin crystal design allows simultaneous measurements with different crystals to investigate different spectral regimes.
