Description
Recent developments at the Paul Scherrer Institute (PSI) include the creation of novel, compact, modular in-vacuum undulators for the upgraded Swiss Light Source, SLS 2.0. One of these new planar insertion devices has already been installed during the ongoing commissioning of SLS 2.0, providing light to its beamline: a 1-meter-long undulator with a 15 mm period length. Another 3-meter-long undulator, with a 17 mm period, integrated keepers for automated field optimization and magnetic force compensation, was recently assembled for the first time and is currently undergoing magnetic characterization. Both devices are automatically optimized within their vacuum chambers; three additional identical 3-meter-long devices are planned.
This contribution covers the status and first magnetic results of these novel in-vacuum undulators, including insights into the magnetic measurement and optimization systems. Furthermore, initial experience from commissioning and performance is presented.
