Development of fast one-dimensional X-ray detector for imaging of explosions

Investigation of fast dynamic processes (explosions) with the help of synchrotron radiation allows to understand properties of matter at very high temperatures and pressures. Detector for such studies has to be able to detect X-ray photons from each electron bunch separately with position resolution of about 0.1 mm.The prototype of detector for imaging of explosions at SR beam (DIMEX) is described in the paper. Spatial resolution of ∼300 μm (FWHM) and time resolution of ∼100 ns is demonstrated with SR beam from 2 T wiggler at VEPP-3 and electron beam energy of 2 GeV.Results of the first experiments on projective imaging and small angle scattering (SAXS) are presented.
