AB  - Interruptions in the functioning of linear superconductive accelerators LLRF (Low-Level Radio Frequency) systems can result in significant downtime. This can lead to lost productivity and revenue. Accelerators are foreseen to operate under various conditions and in different operating modes. As such, it is crucial to have flexibility in their operation to adapt to demands. Automation is a potential solution to address these challenges by reducing the need for human intervention and improving the control’s quality over the accelerator. The paper describes EPICS-based tools for LLRF control system testing, optimization, and operations support. The proposed software implements procedures and applications that are usually extensions to the core LLRF systems functionalities and are performed by operators. This facilitates the maintenance of the accelerator and increases its flexibility in adaptation to various work conditions and can increase its availability level. The paper focuses on the architecture of the solution. It also depicts its components related to superconducting cavities parameters identification and elements responsible for their tuning. Since the proposed solution is destined for the European Spallation Source control system, the application has a form of multiple IOCs (Input/Output Controllers) wrapped into E3 (ESS EPICS Environment) modules. Nevertheless, it can be adjusted to other control systems - its logic is universal and applicable (after adaptations) to other LLRF control systems with superconducting cavities.

AB  - The Radio Frequency Protection Interlock system plays vital role in the LLRF related/dependent accelerator sections Protection. It’s main role is to collect information from number different sensors and indicators around nearest cavities and cryomodule and provide instant RF signal termination in case of safety thresholds violation. This submission describes newly designed RFPI system tailored to the Proton Improvement Plan II (PIP-II) requirements. The proof of concept prototype of this system has been build. The paper includes also the CMTF environment evaluation tests results and findings as an input to the next full-scope prototype design.
