Beam Analysis for the Large Hadron Collider

Wire scanners are used in the Large Hadron Collider (LHC) to obtain measurements of the beam profile during low intensity calibration runs. These measurements are used to calibrate Beam Syncrotron Radiation Telescopes (BSRTs) which can be used to obtain beam profiles during high intensity data runs. This paper examines emittance, brightness, and intensity measurements obtained through wire scanner aquisition for calibration fills 6699 and 6913. Wire scanners can also be used to collect beam profile information during the injection phase of normal runs. This paper demonstrates that the data collected by the wire scanner during the normal runs is faulty.
