Measurement of Magnetic Axis in Accelerator Magnets : Critical Comparison of Methods and Instruments
/ Bottura, L ; Buzio, M ; Pauletta, S ; Smirnov, N
We review 19 measurement systems for the magnetic axis of accelerator magnets, used to align machine components. First, we provide some background information and we describe briefly the instruments and methods used for the magnetic and the geometric measurements. [...]

Data Analysis of Transient Energy Releases in the LHC Superconducting Dipole Magnets
/ Calvi, M (CERN) ; Angrisani, L (Naples U.) ; Bottura, L (CERN) ; Di Castro, M (CERN ; Naples U.) ; Masi, A (CERN) ; Siemko, A (CERN)
Premature training quenches are caused by transient energy released within the LHC dipole magnet coils while it is energized. Voltage signals recorded across the magnet coils and on the so-called quench antenna carry information about these disturbances. [...]

A Hall Plate Based Instrument to Measure the Snapback in the Large Hadron Collider Superconducting Dipole Magnets
/ Sammut, N J ; Benedico-Mora, E ; Bottura, L ; Galbraith, P ; Giloteaux, D ; Greco, G ; Haverkamp, M ; Marchesotti, M ; Masi, A ; Micallef, J et al.
The decay and snapback of the magnetic field multipoles in superconducting particle accelerators like the Large Hadron Collider (LHC) could result in a significant particle beam loss unless adequately compensated. Whilst standard instrumentation used to measure the field quality of the superconducting magnets is good enough to measure the harmonic decay, it is not fast enough to measure the snapback. [...]

A Device to Measure Magnetic and Mechanical Axis of Superconducting Magnets for the Large Hadron Collider at CERN
/ Buzio, M ; Galbraith, P ; García-Pérez, J ; Laface, E ; Pauletta, S
The LHC will be composed of 1232 horizontally curved, 15 meter long, cryodipoles and 474 Short Straight Sections, being assembled by different manufacturers. Magnetic axis alignment is an essential part of the magnets quality for two reasons: first, to be able to install correctly the magnets in the tunnel w.r.t. [...]
