Abstract
The described detector for imaging of explosions (DIMEX) has been designed for the studies of fast processes (explosions, combustion) at synchrotron radiation (SR) beam. DIMEX has been in operation on the SR beam-line on the VEPP-3 electron ring at Budker INP since 2002. DIMEX is based on a one-coordinate gas ionization chamber filled with a Xe–CO2 (3:1) mixture at 7 atm and active Frisch-grid made of a Gas Electron Multiplier (GEM). The detector has a spatial resolution of 0.2 mm and dynamic range of ∼ 100 , which allows one to achieve a signal measurement precision of a few percent. The future possibility to install a similar detector on the SR beam-line on the VEPP-4 electron ring is discussed and the last version of the detector is described.
