Single-Bunch Monitor of the Position and Intensity of the SR Beam for Station "Fast Processes" of the Synchrotron Radiation Facility "SKIF"

The design of a fast monitor of the synchrotron radiation beam position and intensity is described in the paper, which is being created for the station 1-3 "Fast Processes" of the synchrotron radiation facility "SKIF". This monitor will be used for correction of the results of the measurements performed with the specialized detector for experiments with fast processes. Such corrections are necessary because the bunches in the storage ring have different currents and might have different positions and angles during their passage through the wiggler. The monitor will consist of 4 channels, in each channel the signal is formed by current pulses. Each channel will include an integration circuit to convert current into voltage, and an analogue-to-digital converter to digitize the received signal. The digitized signal will be fed into a programmable logic integrated circuit, after which it will be sent to a computer via Ethernet interface. This article describes the operating principles of the device, as well as the results obtained so far.
