Abstract :
Emittance growth due to noise from a transverse beam feedback system are discussed. A theory for calculating emittance growth rate as a function of the feedback system´s measured open loop transfer function is derived. A simple feedback system was installed, measured, and tested in the Fermilab Tevatron, and the emittance growth rate results agree very closely with the theory
