Further development of the detector for imaging of explosions, present status.



Primary authors


Detector for imaging of explosions (DIMEX) is successfully exploited at the Siberian Synchrotron Radiation Center for more than ten years. DIMEX can measure spatial distribution of SR after an exploding sample from individual bunches without mixing radiation from them. Recent upgrade of the gaseous version of the detector with custom ASIC DMXG64 allowed to increase the number of stored frames in an experiment from 32 to 100 and improve rate capability from 2 MFrames/s to 8 MFrames/s. The new version of DIMEX-G is operating at two stations at beam line 0 at the VEPP-3 and at beam line 8 at the VEPP-4M storage rings. Further improvement of the parameters of the DIMEX will be achieved with the Si-strp technology. The new prototype detector DIMEX-Si is assembled based on Si-strip sensor with 96 channels with 50 microns pitch and with electronics based on new custom ASIC DMXS6A with 32 analog memory cells in each channel. The new ASIC allows to reach rate capability of 50 MFrames/s and increase maximum registered photon rate by two orders of magnitude as compared to DIMEX-G.
