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