Synchrotron Radiation Measurements at the CERN LHC

The CERN LHC is equipped with two systems (one for each beam) designed to image the synchrotron radiation emitted by protons and heavy ions. After their commissioning in 2009, the detectors were extensively used and studied during the 2010 run. This allowed preliminary limits in terms of sensitivity...

description The CERN LHC is equipped with two systems (one for each beam) designed to image the synchrotron radiation emitted by protons and heavy ions. After their commissioning in 2009, the detectors were extensively used and studied during the 2010 run. This allowed preliminary limits in terms of sensitivity, accuracy and resolution to be established. The upgrade to an intensified video camera capable of gating down to 25ns permitted the acquisition of single bunch profiles even with an LHC proton pilot bunch (~5e9 protons) at 450 GeV or a single lead ion bunch (~1e8 ions) from about 2 TeV. Plans for the optimization and upgrade of the system will be discussed. For the last few months, part of the extracted light is deviated to the novel Longitudinal Density Monitor (LDM), consisting of an avalanche photo-diode detector providing a resolution better that 100 ps. The LDM system description will be complemented with the promissing first measurement results.
