Description
In 2026, commissioning of the SRF SKIF facility, a 4+ generation synchrotron radiation source accelerator complex was initiated. The facility comprises a 200 MeV electron linear accelerator, a booster synchrotron accelerating electrons to 3 GeV, and a storage ring equipped with superconducting insertion devices for SR generation.
Approximately 2,500 power supplies are used to control the magnets of the accelerator complex. Their operation is managed by embedded controllers capable of regulating specified output parameters, such as current or voltage. The controllers support synchronization of both the execution of specified setpoints and measurement of the actual output values with external clock pulses provided by the timing system at a frequency of 10 kHz. The control and monitoring processes are synchronized with the cyclic motion of the electron beam. This approach enables detailed monitoring of the power-supply and beam parameters and facilitates the detection of instabilities in the operation of the accelerator systems and devices.
This paper presents the control system for the magnetic elements of the SKIF accelerator complex based on embedded controllers, as well as the architecture of the embedded controller itself.
