“…Furthermore, 'inclined' linear polarization is available as reported in the previous paper (Tanaka & Kitamura, 2011a), as well as the HPR and VPR. Note that the structure of the mechanical frame becomes more complicated to realize the above scheme, because all of the six arrays should be shifted along the longitudinal axis independently; it is worth mentioning, however, that such an ID to allow for the phase motion of six arrays has been constructed before (Tsuchiya et al, 2016).…”

An insertion device capable of switching the operation mode between helical and figure-8 undulators, and thus referred to as a helical-8 undulator, has been developed. It has the advantage that the on-axis heat load can be kept low regardless of the polarization state, even when a high K value is required to lower the fundamental photon energy. This is in contrast to conventional undulators in which the on-axis heat load tends to be significantly high to generate linearly polarized radiation with a high K value, and optical elements can be seriously damaged. The principle of operation, specification and light source performance of the developed helical-8 undulator are presented together with further options to enhance its capability.

“…In February 2015, this insertion device was replaced by an APPLE-II (advanced planar polarized light emitter II) type elliptically polarizing undulator (EPU), U#13. The period length and the periodicity number of the APPLE-II EPU are 7.6 cm and 47, respectively (Tsuchiya, 2015;Tsuchiya et al, 2016). The undulator enables linear polarized radiation (horizontal and vertical), circular polarized radiation (left and right), and elliptical polarized radiation (left and right) to be generated.…”

Beamline 13 of the Photon Factory has been in operation since 2010 as a vacuum ultraviolet and soft X-ray undulator beamline for X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and angle-resolved photoelectron spectroscopy (ARPES) experiments. The beamline and the end-station at branch B have been recently upgraded, enabling microscopic XPS, XAS, and ARPES measurements to be performed. In 2015, a planar undulator insertion device was replaced with an APPLE-II (advanced planar polarized light emitter II) undulator. This replacement allows use of linear, circular, and elliptical polarized light between 48 and 2000 eV with photon intensities of 109–1013 photons s−1. For microscopic measurements, a toroidal post-mirror was renewed to have more focused beam with profile sizes of 78 µm (horizontal) × 15 µm (vertical) and 84 µm × 11 µm at photon energies of 100 and 400 eV, respectively. A high-precision sample manipulator composed of an XYZ translator, a rotary feedthrough, and a newly developed goniometer, which is essential for microscopic measurements, has been used to control a sample specimen in six degrees of freedom, i.e. translation in the X, Y, and Z directions and rotation in the polar, azimuthal, and tilt directions. To demonstrate the performance of the focused beams, one- and two-dimensional XPS and XAS scan measurements of a copper grid have been performed. It was indicated from analysis of XPS and XAS intensity maps that the actual spatial resolution can be determined by the beam size.
