Up to date Vibrating wire magnetic field measurement technique was used in many occasions for alignment of magnets with “zero” field on axis such as quadrupoles, sextupoles and solenoid magnets.
Addressing the need of the next generation of synchrotron radiation sources such as APS-U, ESRF, CHESS-U required precise alignment of quadrupole magnets with dipole field on magnetic axis (CFM),...
The alignment of magnets for particle accelerators has become nowadays highly demanding at metrological level. Furthermore, the reduced beam size in upcoming accelerator projects such as CLIC required for multipole magnets with small bores, where the access for traditional magnetic probes is limited. For these reasons, magnetic field measurement systems based on stretched wires have been...
The next generation of light sources is based on Multi-bend Achromat (MBA) lattices to achieve very low emittances of well below 0.1 nm-rad. In addition to regular dipoles, quadrupoles and sextupoles similar to existing machines, a typical MBA lattice consists of several combined function magnets with strong dipole and quadrupole components. These combined function magnets are also slightly...
The Linac Coherent Light Source at SLAC provided many magnetic measurement challenges. The magnetic center of the quadrupoles was required to be stable as the excitation current was changed for beam based alignment. A rotating coil system was used to measure magnetic center stability. The quadrupoles had to be accurately aligned to undulators and their fiducialization was done with a...
The presentation focuses on the high precision PCB rotating coil for magnetic measurements of both magnets with small size bore (below 10 mm) and big sizes magnets (longitudinal length bigger than two meters).
The design and test results of the new miniaturized synthetic sapphire rotating coil will be presented together with a new innovative design for an adjustable Ribbon coil developed in...
The CERN spin-off company ADAM has designed and is building a 3 GHz linac for proton therapy applications. The linac comprises several rf accelerating units which allows to accelerate protons up to 230 MeV in about 25 meters. The focusing lattice is based on FODO cells made of compact small aperture Permanent Magnet Quadrupoles (PMQ) placed between the accelerating tanks. A general...
ALBA is a third generation Synchrotron Light Source operating close to Barcelona since 2012. A magnetic measurements laboratory associated to the facility since its very early stages has been active for the last 20 years. In the first part of the present contribution the different instruments available at the laboratory are described, and a brief overview of the measurement campaigns carried...
