Outline of Final Research Achievements |
Using a test bench consisted of five multi-pole magnets with typical field gradients, we demonstrated an alignment of these magnets by introducing a vibrating wire method (VWM). The background fields, geomagnetism, remanent of another magnets, were canceled by counter dipole and quadrupole magnets. An overall statistical error of the system was estimated to be +-5um using a linearity controlled wire. In order to observe a drift of the magnetic center caused by temperature rise of a water-cooling magnet, and caused by a deformation after installation, etc., we developed a resonance-frequency tracked vibrating wire for a sustainable measurement. A precise alignment system with an accuracy of micro-meter order was completed for a ultra-low emittance ring.
