Description
The RF Test Facility (RFTF) at the Spallation Neutron Source (SNS) is used for RF conditioning of components such as ceramic windows and couplers prior to their installation in charged-particle accelerators. This process involves exposing components to high-power RF fields and thermal cycling to improve performance and remove impurities. To automate and optimize this process, a Python-based EPICS control system was developed, along with hardware upgrades. The system enables real-time monitoring and control of RF power levels, temperature, and vacuum pressure. A user-friendly graphical interface was implemented using CS-Studio (Phoebus), allowing operators to adjust parameters and collect data efficiently. The system integrates the High Power Protection Module (HPM) for interlocks based on vacuum and arc detection, ensuring safe operation. These upgrades have significantly improved the efficiency, accuracy, and safety of RF conditioning at the SNS RFTF. This presentation introduces the updated RF conditioning system, highlighting the software and hardware developments, and its application in support of the Proton Power Upgrade (PPU) project at SNS.
