Phase error correction of superconducting undulator by additional currents

Key Points

The aim is to improve the magnetic field uniformity in superconducting undulators by correcting phase errors.
Developed a correction method using main windings of the undulator.
Grouped windings are powered by additional currents for adjustment.
Graphs were created to analyze phase error across magnetic field ranges.
Total phase error reduced to 3.5 degrees after correction.
Local phase error achieved a minimum of 1.9 degrees at 1.2 T maximum field.

Abstract

We described a method for correcting the magnetic field of a superconducting undulator with neutral poles. For correction, the main windings of the undulator are used, grouped into separate groups and powered by additional currents. Graphs of phase errors are presented for the entire range of magnetic fields of the undulator after correction. The magnitudes of the total and local phase errors were 3.5 and 1.9 degrees for a maximum field of 1.2 T.
