A New Low Level RF System for the Fermilab Booster

A new low level RF system featuring improved bandwidth, dynamic range, filtering, and signal processing has recently been commissioned in the Fermilab Booster. Two analog feedback loops lock the frequency and the phase angle of the RF accelerating voltage to the proton beam. Programmed curves such as frequency and gain can be corrected by a software feedback loop which processes digitized error signals. System performance and operational experience will be discussed.
