Tunable Microwigglers for Free-Electron Lasers

摘要

The design, construction, and test results of a novel microwiggler structure with a periodicity of 2.4 mm are presented for free-electron laser applications. The experimentally demonstrated tunability of field amplitude provides versatile means for field tapering, optical klystron configurations, improving field uniformity, and electron beam matching at the wiggler entrance.
