A new walking-mode for an elliptical polarized undulator is introduced to save machine-study time for feed-forward scanning.
research papers
The propagation of the transverse electric modes in a plasma-filled waveguide with an elliptical cross-section is investigated, and the field components, the cut-off frequencies and the electron beam trajectory are calculated.

Polarization calibration of the photon beam produced by an APPLE-II undulator using a multilayer-based soft X-ray polarimeter is presented.
research papers
The complete polarization analysis for both the linear arbitrary polarization and the various ellipticities of an APPLE II undulator using a multilayer-based soft X-ray polarimeter is shown.
research papers
The polarization capabilities of SwissFEL's Athos beamline are demonstrated by deriving the Stokes parameters as a function of the undulator phase and comparing them with experimental measurements obtained by cold target recoil ion momentum spectroscopy.
research papers
The operation of an undulator which produces linearly polarized X-rays at various angles is described. Using the new technique, linear dichroism measurements of oriented polymer films are obtained on beamline 4.0.2 at the ALS.
insertion devices
A helical undulator was installed in the 0.75 GeV storage ring of the UVSOR facility of the Institute for Molecular Science. The undulator was designed to produce the fundamental of the circularly polarized undulator radiation in the energy range 2-43 eV, and the higher harmonics with elliptical polarization in the energy range up to 300 eV. Recently, the first spectrum from the undulator was observed. The performance of the undulator and the obtained spectrum are reported.
research papers
The degree of circular polarization of soft X-rays emitted from the multi-polarization-mode undulator of BL17SU at SPring-8 was measured by means of magnetic circular dichroism in core-level X-ray absorption spectroscopy.
research papers
The design and performance of the Apple-Knot undulator which can generate photons with arbitrary polarization and low on-axis heat load are presented.
research papers
This theory demonstrates the existence of a variable transverse K gradient in Apple-type undulators. It is supported by numerical simulations to assess the limits of this analytical approach.
