Continuous development of the RF power amplifiers, the waveguide system and the measurement and protection devices provides reliable operation and improves the performance of the RF System. In this article, operation and maintenance procedures of this RF system are analysed and recent as well as future upgrades are being analysed and discussed. In particular, we discuss the improvements of the transmission line's VSWR monitor and its effect on the protection of the RF system against RF breakdowns and sparks. We discuss the new version of the input circuit that was installed, tested and is currently used in the final stage of RF power amplifier. We analyse various schematics and configurations of the Intermediate Power Amplifier (IPA) to be deployed in the future.
