Observation of Beam Instabilities with very tight Collimation

We report about the observation of instabilities in the LHC in special runs with high beta* and very tight collimation down to 2 sigma which increases the transverse impedance significantly. The losses appeared primarily on the highest intensity, non-colliding bunches which can be interpreted as evi...

description We report about the observation of instabilities in the LHC in special runs with high beta* and very tight collimation down to 2 sigma which increases the transverse impedance significantly. The losses appeared primarily on the highest intensity, non-colliding bunches which can be interpreted as evidence for insufficient Landau damping. We describe the beam conditions, observations and possible explanations for the observed effects.
