Description

The conditioning of RF components and their proper storage are crucial for stable and reliable Linear Accelerator (LINAC) operation. The Radio-Frequency Test Facility (RFTF) was built to test the RF subsystems and to condition the RF windows and couplers of the LINACs at the Spallation Neutron Source (SNS). It consists of two waveguide systems operating at 402.5 MHz and 805 MHz, powered by klystrons rated up to 5 MW peak power at 8% duty cycles. The system utilizes the High Power Protection Module (HPM) for interlocks from vacuum and arc detection. A Python EPICS control software and the CS-Studio (Phoebus) user interface were developed and implemented to automate and optimize the conditioning process, providing real-time monitoring of RF power levels, temperature, and vacuum pressure. The system has been used for evaluating, testing, and conditioning the klystrons, circulators, and SRF couplers for the Proton Power Upgrade (PPU) project. This presentation introduces the RF conditioning system updates through software developments and hardware upgrades made at the SNS RFTF and discusses the utilization of the system for the PPU projects at SNS.
