Synchrotron Radiation Technological Station at the VEPP-4M Storage Ring

Abstract

On the beam line № 1 of the VEPP-4M storage ring located at the Institute of Nuclear Physics named after Budker SB RAS, a new technologically oriented terminal station has been put into operation. First of all, the station is intended for conducting visual didactic experiments with an active beam for teaching university students of related training profiles and novice users, developing and testing measuring instruments, as well as conducting preliminary or additional measurements. Such a direct involvement of students into the design of beamline components and deployment of different synchrotron techniques increase their motivation towards professional and efficient utilization of synchrotron radiation techniques and instrumentation development, which is highly demanded for the ongoing project SRF SKIF. The modular design of the end station enables implementation of diverse techniques in the mode of continuous upgrade. The present paper describes the optical scheme of the beamline and emphasizes synchrotron beam parameters therein with respect to other beamlines operating in the Budker Institute of Nuclear Physics SB RAS. Selected examples of experimental results obtained by students using various techniques in the course of training are given. In particular, the automized operation of a photodiode-based X-ray beam monitor is demonstrated, which is required to visualize the incident X-ray beam, measure its exact position and intensity. The implementation of X-ray fluorescence analysis technique in a dedicated vacuum chamber enables quantification of light elements, which was unattainable at other beamlines. Prospects for further development of the technology-oriented end station are envisage.
