In the frame of the EG-5 accelerator modernization project, the authors of the report developed an automated system for positioning and stabilizing the position of the ion beam (ASPSIB) in the ion guide of the EG-5 accelerator based on 4 current sensors and an electromagnetic deflection system (ESA, Fig.1.).

Calculations, modeling of processes in electrical circuits, tests on an optical layout were carried out.

The report will consider the principle of operation of the system, the main elements, the results of modeling and proposals for the development of this option.
