Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：International Centre for Diffraction Data
A mathematical system for modeling the effects of symmetrized instrumental aberrations has been developed. The system is composed of the truncated Gaussian, sheared Gaussian and Rosin-Rammler type functions. The shape of the function can uniquely be determined by the standard deviation and kurtosis. A practical method to evaluate the convolution with the Lorentzian function and results of application to analysis of experimental powder diffraction data are briefly described.

Equatorial aberration for powder diffraction data collected by continuous scan of a silicon strip X-ray detector Invited Reviewed International journal
Takashi Ida
Powder Diffraction 64 ( 3 ) 169 - 175 2021.09
Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：International Centre for Diffraction Data
Application of continuous-scan integration to collect X-ray diffraction data with a Si strip X-ray detector (CSI-SSXD) introduces additional effects on the peak-shift and deformation of peak shape caused by the equatorial aberration. A deconvolutional method to correct the effects of equatorial aberration in CSI-SSXD data is proposed in this study. There are four critical angles related to the effects of spill-over of the incident X-ray beam from the specimen face in the CSI-SSXD data. Exact values of cumulants of the equatorial aberration function are efficiently evaluated by 4×4 point two-dimensional Gauss-Legendre integral. A naïve two-step deconvolutional method has been applied to remove the effects of the first and third-order cumulants of the equatorial aberration function from the observed CSI-SSXD data. The performance of the algorithm has been tested by analyses of CSI-SSXD data of three LaB6 powder specimens with the widths of 20, 10 and 5 mm, collected with a diffractometer with the goniometer radius of 150 mm.

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：International Centre for Diffraction Data
A deconvolutional method for preprocessing powder diffraction data has been improved. The cumulants of instrumental aberration functions of Bragg-Brentano (Parrish) diffractometer calculated up to the fourth order are presented. The treatments of axial-divergence aberration and the effective spectroscopic profilee of the source X-ray have been simplified from those used in the previous methods. The current method has been applied to powder diffraction data collected with a Cu-target X-ray tube, used over 20 years, and a N-foil K_beta filter.

Deconvolution–convolution treatment on powder diffraction data collected with CuKα X-ray and NiKβ filter Reviewed International journal

Powder Diffraction 33 ( 2 ) 80 - 87 2018.06
Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：International Centre for Diffraction Data
A method to remove small CuKβ peaks and step structures caused by NiK-edge absorption as well as CuKα2 sub-peaks from powder diffraction intensity data measured with Cu-target X-ray source and Ni-foil filter is proposed. The method is based on deconvolution–convolution treatment applying scale transform of abscissa, Fourier transform, and a realistic spectroscopic model for the source X-ray. The validity of the method has been tested by analysis of the powder diffraction data of a standard LaB6 powder (NIST SRM660a) sample, collected with the combination of CuKα X-ray source, Ni-foil Kβ filter, flat powder specimen and one-dimensional Si strip detector. The diffraction intensity data treated with the method have certainly shown background intensity profile without CuKβ peaks and NiK-edge step structures.

Concept of deconvolution-convolution treatment on powder X-ray diffraction data Reviewed

Annual Report of Advanced Ceramics Research Center, Nagoya Institute of Technology 5 37 - 43 2017.06
Authorship：Lead author Language：Japanese Publishing type：Article, review, commentary, editorial, etc. (bulletin of university, research institution) Publisher：Advanced Ceramics Research Center, Nagoya Institute of Technology
This article introduces the core concept of a deconvolution-convolution treatment (DCT) on powder diffraction data, recently proposed by the author. The method is based on a realistic spectroscopic profile of X-ray and the results of cumulant analysis of a precise approximate formula for the axial-divergence aberration in Bragg-Brentano geometry. It is demonstrated that the powder diffraction data treated by the method show almost symmetric single peak profile, and small unwanted contamination peaks in the observed data are effectively removed by the method.

Application of Bayesian inference to structure analysis Reviewed
Takashi Ida
Annual Report of Advanced Ceramics Research Center, Nagoya Institute of Technology 3 11 - 16 2015.07
Authorship：Lead author Language：Japanese Publishing type：Article, review, commentary, editorial, etc. (bulletin of university, research institution) Publisher：Advanced Ceramics Research Center, Nagoya Institute of Technology
The article describes basic concepts of statistical estimation based on experimental data, including (i) Bayesian inference, (ii) maximum a posteriori estimation, (iii) maximum likelihood estimation, (iv) least-squares estimation. It is emphasized that Bayesian inference is nothing but calculation of "conditional probability," which is written in textbooks of high-school mathematics in Japan. Bayesian approach allows prejudice, biased ideas, preconception, and never forces us to get rid of them. The basic concept of Bayesian inference explicitly assumes that we can never reach the absolute truth, but we can always approach to the truth at the same time. A simple implementation of Bayesian inference in crystal structure analysis based on X-ray diffraction measurements is proposed.

反射型の粉末回折測定では，通常はＸ線侵入深さに比べて試料が充分な厚みを持つことを前提とする。試料の厚さが有限な場合，試料の透過性の効果は，回折角依存性の異なる減衰効果と打ち切り効果の二重の畳込として表現される。打ち切り効果に関する逆畳込的処理はピークのブロードニングをもたらすが，ピーク形状が尖鋭化し，ピーク分離の目的で不利にならないことがわかった。
