Bunched-beam Schottky monitoring in the LHC / Betz, M (LBL, Berkeley) ; Jones, O R (CERN) ; Lefevre, T (CERN) ; Wendt, M (CERN)
The LHC Schottky beam diagnostic system has the potential to measure beam parameters such as tune, chromaticity and momentum spread in a non-invasive way. It does so by detecting beam induced signals at 4.8 GHz, and extracting the characteristic modulation caused by incoherent motion of particles within a bunch. [...]

Upgrade of the LHC Schottky Monitor, Operational Experience and First Results / Betz, Michael (CERN) ; Jones, Owain Rhodri (CERN) ; Lefèvre, Thibaut (CERN) ; Wendt, Manfred (CERN)
The LHC Schottky system allows the measurement of beam parameters such as tune and chromaticity in an entirely non-invasive way by extracting information from the statistical fluctuations in the incoherent motion of particles. The system was commissioned in 2011 and provided satisfactory beam-parameter measurements during LHC run 1 for lead-ions. [...]

A magnetic quadrupole pick-up for the CERN PS / Chapman-Hatchett, A ; Jansson, A ; Williams, D J
In the LHC era, there will be a need to monitor and correct betatron mismatch between machines in a non-destructive way. For this purpose, a quadrupole pick-up has been designed for the CERN PS. [...]

Microwave Schottky diagnostic systems for the Fermilab Tevatron, Recycler, and CERN LHC / Pasquinelli, Ralph J ; Jansson, Andreas
A means for non-invasive measurement of transverse and longitudinal characteristics of bunched beams in synchrotrons has been developed based on high sensitivity slotted waveguide pickups. [...]

The magnetic quadrupole pick-ups in the CERN PS / Jansson, A
The idea of using non-linearities of beam position monitors to measure the second moment sx2 - sy2 of the transverse beam distribution is almost as old as the synchrotron. However, although a few successful experiments have been reported, the method has not become widely accepted. [...]

Impact of second-order chromaticity on the Schottky spectra of bunched beam / Lasocha, Kacper (CERN) ; Alves, Diogo (CERN) ; Lannoy, Christophe (CERN ; Ecole Polytechnique, Lausanne) ; Mounet, Nicolas (CERN)
Observation of Schottky signals provides information on important beam and machine parameters, such as transverse emittance, betatron tune, and first-order chromaticity. However, the so-far developed theory of Schottky spectra does not include the impact of the higher-order chromaticity, known to be non-negligible in the case of the Large Hadron Collider (LHC). [...]

Improvements to the LHC Schottky Monitors / Wendt, Manfred (CERN) ; Betz, Michael (CERN) ; Jones, Owain Rhodri (CERN) ; Lefèvre, Thibaut (CERN) ; Levens, Thomas (CERN)
The LHC Schottky monitors have the potential to measure and monitor some important beam parameters, e.g. tune, momentum spread, chromaticity and emittance, in a non-invasive way. [...]
