Tune measurement methods in the Fermilab Main Ring

The Fermilab Main Ring has three different systems for measuring the betatron tune. The three systems are designed around a resonant beam pickup which interfaces to independent data collecting hardware. The data collecting hardware systems consist of a Hewlett Packard 35665A dynamic signal analyzer, a Tektronix 3052 DSP and a generic finite state data acquisition (GFSDA) microprocessor system. This paper will describe the systems and the methods for measuring the betatron tune and chromaticity in the Fermilab Main Ring.
