Abstract :
A measurement system of the betatron tune is operational at the AGS (Alternating Gradient Synchrotron), and one for the AGS Booster is under development. Both systems use ferrite kicker magnets to excite coherent betatron oscillations. Difference signals are sampled at the revolution frequency and the tune is extracted from a fast Fourier transform. Details of the hardware of both systems are described, as well as all the features of the application program through which the operator interacts with the hardware. The AGS system and the booster system are described.<>
