Abstract :
The guide field magnets in CESR have a frequency response of 0.5 Hz. To allow fast control of betatron tunes we have installed a system of air core quadrupoles. We describe the air core quadrupoles and present results of tests of the system for tune control, hysteresis free beta function measurements, and tune feedback.
