Two in-vacuum undulators (length 2 m) with period 22 mm (IU22) are constructed to be
installed in the Taiwan Photon Source (TPS, 3 GeV) to provide a highly brilliant light source …

Short period undulators to be used as FEL radiators permit lower electron energies and,
thus, reduced linac and undulator lengths. The first X-ray FEL facility based on in-vacuum …

With permanent magnet undulators operating at cryogenic temperature, the magnetic field
and coercivity are enhanced, enabling shorter periods with higher magnetic field. The first …
