Machine learning assisted masking of parasitic signals in Bragg coherent diffraction imaging

open access: yesJournal of Synchrotron Radiation, EarlyView.
Bragg coherent diffraction imaging measurement sometimes requires manual and time‐consuming cleaning of parasitic signals termed `aliens' from nearby particles that can affect the phase retrieval reconstruction. Here, we propose using a clustering technique to speed up this process while keeping the resolution of the reconstructed object high.

Proposal of a novel APPLE‐KNOT undulator by selecting the KNOT field as the dominant magnetic field

open access: yesJournal of Synchrotron Radiation, EarlyView.
The degradation of circular polarization state in conventional APPLE‐KNOT undulators has been noted. To overcome this limitation, we propose a novel APPLE‐KNOT undulator design which utilizes the KNOT magnetic field as the dominant component.The APPLE‐KNOT undulator forms composite magnetic fields by superimposing an APPLE field and a KNOT field with ...

Primitive icosahedral quasicrystals in ZnMgLi(Dy, Ho, Er, Tm) systems

open access: yesActa Crystallographica Section A, EarlyView.
The study introduces new primitive icosahedral quasicrystals in Zn–Mg–Li–(Dy, Ho, Er, Tm) systems. Quasicrystals are studied with an X‐ray diffraction technique resolving the local atomic structure.New quasicrystals with rare‐earth elements and Li are synthesized with the self‐flux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.

Exploring oxide quasicrystals in internal space

open access: yesActa Crystallographica Section A, EarlyView.
The internal space expansion with variable system size is investigated for three different oxide quasicrystal systems. Patches of 7800, 4800 and 3600 vertices are examined in Ba–Ti–O/Pt(111), Eu–Ti–O/Pd(111) and Sr–Ti–O/Pd(111), respectively. This internal space inspection provides unique structural information for quasicrystalline systems, which goes ...
