Fast Synchrotron Radiation beam Position and Intensity Monitor for the Experiments to Study Fast-Flowing Processes

Abstract

To study detonation and shock wave processes as part of experimental stations at the SKIF Center for Shared Use, it is planned to build a “Fast Processes” station. The station will include DIMEX detectors (Detector for imaging of explosions). DIMEX is capable of detecting synchrotron radiation (SR) from each electron bunch in the storage ring. Since bunches can deviate from the equilibrium orbit and differ in current, to increase the accuracy of signal magnitude measurements, a fast monitor of the position and intensity of the SR beam is needed, measuring the relative position and power of the beam radiation from each electron bunch in the storage ring. The readings from this monitor will be used to correct the measurements of the DIMEX detectors. As part of the fast SR beam position monitor, it is planned to place 4 sensors that measure the signal in the vicinity of the beam at the top, bottom, right and left. When the beam position changes, the signal ratios in the corresponding pairs of sensors will change. When the total SR flow changes, the sum of the signals from all sensors will change. The beam monitor, synchronously with the operation of the DIMEX detector, will record signals from all sensors during the experiment. After the experiment, the results recorded from the DIMEX detector will be adjusted in accordance with the monitor sensor signals.
