Collimator Sounds


Sound of a beam impacting on a carbon-carbon jaw A microphone was placed close upstream of the LHC collimator. Downstream of the collimator was the beam dump. The jaw of the collimator was moved into the path of the extracted LHC-type SPS beam. Once extracted, the full beam intensity was put onto one collimator jaw with transverse impact parameters between 1 mm and 5 mm. Such a test of robustness against shock beam impact was performed.
