Fig. 2 in the article by Yamazaki et al. [(2026). J. Synchrotron Rad. 33, 84–90] contained an inconsistency that has been corrected without affecting the results or conclusions.
Keywords: channel-cut monochromators; double channel-cut; cryogenic cooling; thermal deformation; beam stability; fixed-exit geometry; fourth-generation synchrotron radiation.
In the originally published version of Fig. 2![[link]](../../../../../../logos/arrows/s_arr.gif){kind=small}
in Yamazaki et al. (2026), the beam paths were not consistent with the photon energies specified in the figure caption, which could lead to a misleading interpretation. Fig. 2 has been replaced with a revised version having consistent beam paths and auxiliary lines to clarify the geometrical relation used in the thermal estimation.
![[Figure 2]](vy9044fig2thm.gif) | Figure 2 Design of the first channel-cut crystal. All dimensions are in millimetres. Bragg angles were varied by θ rotation of the crystal about the  axis. Red and blue lines represent beam paths relative to the crystal orientation at photon energies of 4.46 keV and 24.8 keV, respectively. Higher-energy components in the incident beam escape from the side surface of the first reflecting body. |
