A 3 Ohm PFN was designed with an SCR-based switch and charged to 20 KV with four parallel capacitor-charging power supplies. A 12 MW klystron mounted on a 1:20 pulse transformer powers a six cell, 805 MHz cavity inserted in a superconducting solenoid in the Muon Test Facility. Also a complete set of modulator-klystron interlocks and controls were designed to provide signal monitoring, timing, modulator voltage regulation, as well as interlocking all systems related to the modulator-klystron system. The controls use surface mount technology providing compactness and future technological compatibility. Communication of the system status and data is done through an MVME68040-based system acting as a local node and accepts analog and digital signals relaying them through an Ethernet connection to the main accelerator controls.Presenting Author : Prieto P.
