Title: Magnetic Measurements of the Background Field in the Undulator Hall with Ductwork and Cable Trays

Abstract

The duct work and cable trays present in the undulator hall facility are made out of potentially magnetically active materials. This note describes a measurement done to make a comparison between the fields in the undulator hall with the duct work and cable trays present and in the Magnetic Measurement Facility. In order for the undulators to have the proper tuning, the background magnetic field in the Undulator Hall must agree with the background field in the Magnetic Measurements Facility within 0.5 gauss. To verify that this was the case, measurements were taken along the length of the undulator hall, and the point measurements were compared to the mean field which was measured on the MMF test bench. This set of measurements was conducted with most of the cable trays and duct work in place, but without any of the magnet stands in place.
