Magnetic Measurements


Magnetic Measurements characterize magnetic fields produced by magnetic devices such as dipoles, quadrupoles, combined function magnets, and undulators. At the Berkeley Lab, most of the devices measured are installed in a particle accelerator. The particle beam trajectory and properties depend strongly on the magnetic field. Different measurement techniques are used: Hall probe mapping, rotating coils, wire techniques (stretched wire, pulsed wire, rotating wire) to achieve the desired results. Each of these methods allows us to determine the quality of the magnetic field produced and ultimately the quality of the particle beam itself.
