This note summarises the MD3310 activity. The goal was to measure the complex tune shift as a function of intensity in the LHC at 6.5 TeV. The session took place in the night of 17 June to 18 June 2018 as part of the MD block 1. Bunches of various in

This report summarizes the results of MD1447 about the hierarchy limit of the LHC collimation system in IR7 at 6.5 TeV and its impedance, performed during MD block 1 of 2016. The hierarchy breakage seen in a similar activity in 2015 when deploying 1

This MD allowed confirming that the solenoid installed in 16L2 during Technical Stop 2 (TS22017) could be held responsible for the performance improvement observed after TS2. The MD was performed on 30th November 2017 in parallel with MD#2889 and the

Since the beginning of the LHC commissioning, harmonics of 50 Hz have been observed in the beam spectrum. Several observations during the 2018 proton run show that these harmonics are the result of a real beam excitation, rather than an artifact of t

During run 2 (2015-2018) the LEIR machine experienced several important improvements in terms of extracted intensity, driven by the LHC Injectors Upgrade (LIU) project requirements. In 2018 the machine not only gave another step forward in extracted

The methodology applied in previous MDs has shown the possibility of using BTFs measurements to estimate the transverse Landau Damping of the beams for different machine configurations. However, measurements with beam-beam interactions could not be

During the MD 2722 an unexpected instability was observed at flat top energy during BTF measurements. Simulation studies have shown an decrease of the instability thresholds according to the impedance level when in the presence of a small external e

As signs of electron cloud driven instabilities at top energy were observed in MDs in 2017 even with short trains(12b), an additional experiment was performed in 2018 to assess the intensity scaling of this instability mechanism using high intensity

The Schottky monitors installed at the LHC enable the detection of Schottky noise of the two circulating proton / ion beams. From Schottky noise, beam parameters like tune, chromaticity, and relative emittance, can be extracted in a non-destructive a
