One-dimensional detector for study of detonation processes with synchrotron radiation beam

摘要

Detector for the studies of very fast processes (explosions, detonation waves, etc.) at a synchrotron radiation (SR) beam is described. The main feature of such device is to be able to detect SR photons from each electron bunch separately with the position resolution of about 0.1 mm. The first prototype of the detector for imaging of explosions demonstrated spatial resolution of ～ 200 μ, time resolution of ～ 50ns and dynamic range of ～ 100 with white SR beam from 2 T wiggler and electron beam energy of 2 GeV. Results of the first experiments on projective and SAXS imaging are presented.
