Description

Currently, the Flerov Laboratory of Nuclear Reactions (FLNR) is modernizing its accelerator complex, focusing on the development of new facilities and the enhancement of existing ones. Notably, the U400M cyclotron has been successfully modernized. As part of the upgrade of the U400M's main systems, a project for the deep modernization of its Automated Radiation Monitoring System (ARMS) was initiated.
In addition to monitoring the radiation environment of the U400M, the ARMS oversees other radiation-related facilities in the main building at FLNR. These include the MT-25 microtron, radiochemical laboratories of the 2nd and 3rd safety classes, and the radioactive isotope storage facility.
This report presents the main types of radiation monitoring implemented by the system, the equipment used, its software features, and the interaction algorithms with the control systems of the U400M and MT-25 accelerators, as well as the U400M Interlock and Signalization System (ISS). Additionally, the current status of the project, challenges in its commissioning, and the prospects for further development of the system at FLNR are discussed.
