The Large Hadron Collider (LHC) was first suggested (in a documented way) in 1983 (S.
Myers and W. Schnell, Preliminary performance estimates for a LEP proton collider, LEP …

Amplitude detuning measurements in the LHC have shown that a significant amount of
detuning is generated via feed-down from high-order field errors in the magnets of the …

This thesis describes the wide subject of the luminosity leveling and its requirements for the
LHC and the HL-LHC. We discuss the advantages and disadvantages of different leveling …

Abstract Direct Diode Detection (3D) is a technique developed at CERN initially for the LHC
tune measurement system, to reach a sensitivity allowing observation of beam betatron …

The LHC is equipped with a full suite of sophisticated beam instrumentation which has been
essential for rapid commissioning, the safe increase in total stored beam power and the …

About 30% of the potential luminosity performance is lost through the different phases of the
LHC cycle, mainly due to transverse emittance blow-up. Measuring the emittance growth is a …

When the LHC beams were in collision during Run 1, ground motion was the dominant
source of orbit changes. Typical drifts over all were below one beam sigma. Maintaining the …

Abstract The Large Hadron Collider (LHC) has now been operated successfully for 3 years
relying on the good performance of its beam instrumentation, including position and tune …

Emittance measurements through the 2012 LHC proton cycle examined possible major
sources for the large blow-up through the LHC cycle already seen in 2011. The behavior of …

The Large Hadron Collider (LHC) was first suggested (in a documented way) in 1983 [1] as
a possible future hadron collider to be installed in the 27 km “LEP” tunnel. More than thirty …
