Design and model tests of a 7.5 T wiggler for the Max-Lab synchrotron radiation facility

A three-pole superconducting wiggler magnet has been designed to provide a peak flux density of 7.5 T. Two-dimensional software was used for narrowing down size parameters and a 3-D program was used for calculating the end fields. The design criteria were maximum peak flux density at minimum overall length and minimum helium boil-off. A 2/3-scale model magnet has been built and tested in order to gain information about the three-pole concept. Experimental verification of the calculated flux densities along the beam track has been obtained.<
