Abstract

The paper focuses on two issues important for the design and operation of bunch-by-bunch transverse damper in a very large hadron collider, where fast damping is required to suppress beam instabilities and noise induced emittance growth. The first issue is associated with kick variation along a bunch that affects the damping of head-tail modes. The second issue is associated with effect of damper noise on the instability threshold. The paper accounts for developments motivated by the discussions at this conference and carried out after it.
