Description
A magnetic measurement test stand has been developed to reduce the workload and time required for the final tuning of the LCLS-II-HE soft X-ray undulators. The test stand includes a touch probe for mechanical measurements, a Hall probe for local field measurements, and a stretched wire system for field integral measurements. The test stand enables early magnetic alignment and magnetic field corrections, including trajectories, phase error, and field integrals. This paper presents the system, its capabilities, and preliminary results demonstrating its use for pre-tuning undulators.
