Title: Long rotating coil system based on stretched tungsten wires for insertion device characterization
Author: Tosin, G

Abstract: A very precise rotating coil was developed using stretched tungsten wires in a new geometric arrangement for the accurate magnetic characterization of insertion devices (IDs). Many sources of errors were analyzed, and a procedure to evaluate coil defects by means of a dipolar magnetic field is presented. Tests were performed in a 2-T planar wiggler, which is 2.8 m long, with 180 mm of period, of the Brazilian Synchrotron Light Source (LNLS). The advantages of using the tungsten wires and the measurement repeatability and accuracy are also discussed.
