Abstract
The described detector for imaging of explosions(DIMEX) has been in operation on the synchrotron radiation (SR)beam-line on the VEPP-3 electron ring at Budker INP since 2002.DIMEX is based on a one-coordinate gas ionization chamber filledwith a Xe-CO2(3:1) mixture at 7atm and active Frisch-grid madeof a Gas Electron Multiplier (GEM). The detector has a spatialresolution of 0.2mm and dynamic range of ∼100, which allowsone to achieve a signal measurement precision of a few percent.The frame rate can be tuned up to 8 MHz (125 ns per image) and asmany as 32 images can be stored in one shot. At present DIMEX isused with the X-ray beam from a 2T wiggler with an average energyof 20 keV. The future possibility to install a similar detectoron the SR beam-line on the VEPP-4 electron ring is discussed.
