Digital Control For KEK-PS MA Loaded RF System
نویسندگان
چکیده
The magnetic alloy loaded radio-frequency system has been installed in the KEK 12 GeV synchrotron. This system is a high field gradient radio-frequency system and is designed to operate not only as a fundamental harmonic system to increase the insufficient matching voltage, supplied by 4 conventional ferrite cavities but also as a second radiofrequency system to alleviate the space charge effects during beam injection. Digital signal processing is the technique to process the continuous machine or beam signals and to couple with a direct digital synthesis, which is the way to generate a phase controlled precise frequency signal. Both techniques are indispensable for the low-level radio-frequency controls of a complex system. Developments of DDS based radio-frequency signal generator and digital phase detector and related ADC modules have been started for this new MA radio-frequency system. The details of R&D equipments are going to be reported.

At the proton linac of the JAERI and KEK Joint Project, an accelerating electric field stability of +-1% in amplitude and +-1 degree in phase is required for the RF system. In order to accomplish these requirements, a digital feedback system is adopted for flexibility of the feedback (FB) and feed forward (FF) algorism implimentation. FPGAs are used for the real-time FB system. A DSP board is a...
