Description
The LHC transverse damper forms part of the RF system and will as such be connected
to the beam interlock system through common links. The system will be used for
injection damping and to provide feedback to stabilize the beams against transverse
coupled bunch modes which could develop at the injection plateau and along the
ramp. From the capabilities of the system limits are derived for the injection
error and instability growth times that the system can handle. Moreover, the damper
can be used for machine studies as beam exciter, and also for active abort gap
cleaning by transverse excitation and subsequent interception of the beam by the
collimation system. These possible uses are described together with their
implications for the machine protection system, such as worst case failure
scenarios including the expected time scale of beam losses as well as possibilities
and limits of protection through interlocks inside the damper system.
