Magnetization Measurement and Sorting of Permanent Magnets for the NovoFEL Variable-Period Undulator

A new variable-period undulator for the Novosibirsk free electron laser facility (FEL) is being developed at the Budker Institute of Nuclear Physics. The undulator has an enlarged aperture, so it uses permanent magnets with a nonstandard shape. In this article, the design of the measuring stand is d...

Zusammenfassung:A new variable-period undulator for the Novosibirsk free electron laser facility (FEL) is being developed at the Budker Institute of Nuclear Physics. The undulator has an enlarged aperture, so it uses permanent magnets with a nonstandard shape. In this article, the design of the measuring stand is described and preliminary results of measurements of the parameters of the magnet are presented.
