Popis: A detector for fast diagnostics of particle beams in storage rings using an optical component of synchrotron radiation (SR) is developed. The detector records a limited series of one-dimensional or small two-dimensional images at a rate of (1−10) × 106 frames/s. It can also be used for investigating fast processes in X-ray SR beams. In particular, matched with a structured scintillation screen (with low deexcitation time), this detector provides a recording with an SR flash rate of shadowgraph images (for axially symmetric objects, initial data for tomograms) or a record of the distribution of small-angle X-ray scattering. It is also possible to apply this detector as a dispersion-free image spectrometer; this would make it possible to perform pulsed X-ray diffraction studies with “white” SR beams. In the single-flash mode this would provide a record of the formation and behavior of crystalline phases in shock and detonation waves with a time resolution of up to 1 ns.
