The LHC collimation system has been re-designed over in order to address the
unprecedented challenges that are faced with the 360 MJ beams at 7 TeV. The layout of the …

Abstract The Large Hadron Collider (LHC) at CERN will collide two counter-rotating proton
beams, each with an energy of 7 TeV. The energy stored in the superconducting magnet …

The fractional part of the betatron tune for a circular accelerator can be measured by
observing beam oscillations on a position pick-up. In frequency domain the betatron …

Upgrades of the CERN particle accelerators complex are planned to increase the potential
of physics discovery in the LHC. In this respect, the beam coupling impedances of the SPS …

The problem of collimation and beam cleaning is one of the most challenging aspects of the
LHC project. A collimation system must be designed, built, installed and commissioned with …

LHC is a source of new challenges in every HEP field; among these, the beam collimation
requires an innovative approach. The H8RD22 collaboration is undertaking an intense study …

The beam commissioning of the LHC collimators is outlined for the expected evolution of
beam intensity and low beta optics in the LHC. Starting from the necessary prerequisites …

A full-scale prototype of the Large Hadron Collider (LHC) collimator was installed in 2004 in
the CERN Super Proton Synchrotron (SPS) and has been extensively used for beam tests …

More or less 30 years ago, it was experimentally demonstrated how a bent crystal can
become a magnet: an object 1 mm thick, a couple of mm wide and a few cm high is, in fact …

Discrete spectra can be used to measure frequencies of signal components. Such a
measurement consists in digitizing the input signal, performing windowing of the signal …
