Description
Summary:Center for Advanced Microstructures and Devices of Louisiana State University (LSU CAMD) is a research center for optimization of synchrotron radiation (SR) for production of soft X-rays. New research projects have necessitated expansion of the SR spectral range to harder X-rays. This task was solved via installation of a superconducting insertion device. This paper presents a description of the superconducting wiggler with a field of 7.5 T made by Budker INP and installed on the storage ring of LSU CAMD. The wiggler consists of 11 main bending magnets with magnetic field with alternating sign and an amplitude of 7.5 T and four side poles (two on each end of the magnet array), which are to make the first and second field integrals in the longitudinal direction equal to zero at any field level of the main poles. The main attention at the designing and production of the magnetic system of the wiggler was paid to the magnetic field quality at all field levels. Presented are results of field magnetic measurements using Hall probes. The dynamic behavior of the first and second field integrals during field ramping up and down, as measured by the method of stretched wire with current, is discussed. The wiggler was installed and successfully commissioned on the CAMD LSU storage ring in 2013.
