Design of the New Control System for Linac-200

The construction of an experimental facility with test electron beams is under way at the Dzhelepov Laboratory of Nuclear Problems at the Joint Institute for Nuclear Research (Dubna, Russia). The facility is based on the MEA accelerator that was transferred from NIKHEF to JINR at the beginning of the 2000s. Despite the long service life of the accelerator, it is in good condition and still has a significant operation potential. The linac is being commissioned and the first 200-MeV beam has been generated. For now, the machine is controlled by a set of standalone subsystems that were created as required. Certain systems (e.g., vacuum) are controlled and monitored locally. However, a global control system is required to operate the accelerator as a user facility. The system requirements are formulated in this paper. The key issues of controlling the accelerator and its auxiliary (evacuation, cooling, etc.) systems are considered. The design of a new Tango-based control system of the Linac-200 is presented.
