Description
Sound and vibration measurements of the LHC collimator were performed
with various accelerometers and a microphone during collimator
robustness tests in 2004 and 2006. The collimator jaws were hit by
450 GeV protons beam of up to 3.5x10e13, equivalent to a total energy
of about 2.4 MJ (0.65% of the nominal LHC beam at 7 TeV). It was
demonstrated that these measurements can be used to detect beam
impacts of LHC beams on the collimators and hence possibly damaged
collimators. In this talk the experimental layout is presented and
detailed frequency analysis of the measured vibration signals are
presented.
