An atomically precise, super smooth, and damage-free surface is highly demanded for x-ray mirrors, multilayer optics, channel-cut crystal monochromators (CCM), and gratings. An ultra-precision optic with a figure error of several nm is crucial for single-nanometer spatial resolution, signal strength, and contrast. Moreover, sub-angstrom root-mean-square surface roughness is beneficial for high reflectivity and the lowest unwanted scattering. Additionally, a damage-free surface with no alter layer is greatly desired for CCM and grating substrates because it is essential for the high reflectivity of the CCM and the uniform etching rate of the grating’s ruling. In the manufacturing of x-ray mirrors, to obtain the desired figure error, a non-contact figuring method, such as ion beam figuring (IBF), plasma chemical vaporization machining (PCVM), or Elastic Emission Machining (EEM), is usually employed thanks to its high controllability and stability. EEM has proved the best performance in terms of achieving a low figure error and maintaining a good surface roughness. After shaping/figuring, a finishing method is usually applied to improve its surface roughness without distorting its figure error. Recently, Catalyst-Referred Etching (CARE) has realized its potential and applicability to x-ray mirror manufacturing as a finishing method. Thanks to its removal mechanism, a highly ordered surface with a root-mean-square of 0.03 nm RMS is attained. In the polishing of a CCM, because a mechanical method is usually used to polish its surface at the narrow gap, the residual mechanical damage induced a low reflectivity and low spatial resolution. PCVM with a wire electrode has recently been proposed and demonstrated its excellent performance. The damage-free surface of a CCM with a gap of less than 100µm has been successfully realized by PCVM. In this paper, recent achievements in figuring (EEM), surface finishing (CARE), and damage removal (PCVM) are presented and discussed.

High resolution imagery of the Sun's X-ray corona provides an essential clue in understanding dynamics and heating processes of plasma particles there. However, X-ray imagery of the Sun with sub-arcsecond resolution has so far never been conducted due to severe technical difficulty in fabricating precision Wolter mirrors. For future X-ray observations of the solar corona, we are attempting to realize precision Wolter mirrors with sub-arcsecond resolution by adopting advanced surface polish and metrology methods to sector mirrors which consist of a portion of an entire annulus, by direct polishing onto the mirror substrate. Based on the knowledge obtained through fabrication of the first (in 2013) and second (in 2014) engineering Wolter mirrors and subsequent evaluations on their X-ray focusing performance, the third engineering mirror was made in 2015−2016. The primary target of improvement over the second mirror was to suppress figure error amplitude especially for spatial frequencies around 1 mm^-1 and to suppress the large astigmatism that was present in the second mirror, by introducing improved deterministic polish and smoothing on the precision mirror surfaces (32.5 mm × 10 mm in area for both parabola and hyperbola segments), as well as by careful characterization of the systematic error in the figure measurement system for the precision polish. Measurements on the focusing performance of thus-fabricated third Wolter mirror at SPring-8 synchrotron facility with 8 keV X-rays demonstrated that the mirror attained sub-arcsecond focusing performance with its HPD (half-power diameter) size reaching as small as ~0.2 arcsec for meridional focusing while ~0.1 arcsec for sagittal focusing. The meridional focusing achieved nearly diffraction limited performance (~0.12 arcsec FWHM for the PSF core). We also confirmed that the large astigmatism noted in the second mirror was correctly removed in the third mirror with the correction of the above-mentioned systematic error.
