Abstract :
With the increase in intensity of the Fermilab Booster accelerator to over 3×1012 p´s/pulse, active dampers have been required to control several transverse and longitudinal instabilities. The damper systems currently in use are: one narrow-band horizontal damper for the (+-Qh) mode, a wideband horizontal damper for all modes, and four channels of narrow-band longitudinal dampers for coupled bunch modes 1, 48, 49, and 50. We discuss the observations that indicated that damper systems were necessary, the designs and operations of the systems, and their effects on beam quality in the Booster
