Development of a one-dimensional detector for the study of explosions with a synchrotron radiation beam

Investigations of fast dynamic processes with the help of synchrotron radiation allow an understanding of the properties of short-lifetime states of materials at very high temperatures and pressures. Detectors for such studies have to be able to detect X-ray photons from each electron bunch separately with a position resolution of about 0.1 mm. A prototype of a detector (DIMEX) for the imaging of explosions at a synchrotron radiation beam is described here. A spatial resolution of 300 µm and a time resolution of 100 ns is demonstrated with a synchrotron radiation beam from the VEPP-3 2 T wiggler at an electron beam energy of 2 GeV. Results of the first projective imaging and SAXS experiments are presented.
