This Master's thesis has been produced at CERN (European Organization for Nuclear
Research) in the Vacuum, Surfaces and Coatings group during an interesting time period for …

The critical and delicate process of dumping the beams of the LHC requires very low particle
densities within the $3\mu $ s of the dump kicker rising edge. High beam population in this …

The application of superconducting materials in the field of high energy accelerator physics
not only opens the doors to the generation of the magnetic fields unattainable to normal …

The LHC upgrade for high luminosity requires an upgrade of the CMS in many parts. One of
the CMS upgrade tasks is to improve the muon tracking and trigger performance, particularly …

The beam collimation systems are an essential part of the high energy colliders. A
collimation system should remove beam halo to reduce detector background and ensure the …

During 2016 operation, all beam dump requests were properly executed by the LBDS.
Nevertheless, many redundant failures in LBDS subsystems occurred, leading to LHC …

The beam collimation systems are an essential part of the high energy colliders. A
collimation system should remove beam halo to reduce detector background and ensure the …

The longitudinal motion of uncaptured particles in the presence of synchrotron radiation is
analysed in detail for the case with RF on. The time scales and the distribution of the …

A two-stage nonlinear collimation system based on a pair of skew sextupoles is presented
for the LHC. We show the details of the optics design and study the halo cleaning efficiency …

As soon as beam is injected into the LHC radiation will be produced in the accelerator
tunnel. Materiel close to the beam will become progressively activated and a source of …
