Dumping the beam

A failure of the LHC Beam Dumping System could have a serious negative impact on the performance of the LHC machine. The failure modes of the Beam Dumping System are presented, together with the expected occurrence rate and possible consequences. For the Beam Dumping System failures that are expected to occur during the LHC lifetime, the functionality and implementation of the...

Dumping the beam

Safe dumping of the LHC beam relies on accurate tracking of the LHC beam energy, since the strength of the dump system elements must scale with the beam energy to obtain the correct extraction trajectories. The LHC Beam Energy Tracking System (BETS) is responsible for the generation of the kick strength reference signals w.r.t. the beam energy of the extraction kicker high voltage...

Dumping the beam

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...
