Zinc Doped Zeolite 13X DIAD X-Ray Diffraction Computed Tomography - 25 and 50 micron spot-size

This repository contains X-Ray Diffraction Computed Tomography (XRD-CT) data of a zinc doped zeolite 13X sample on the Dual Imaging and Diffraction (DIAD / K11) at Diamond Light Source.

XRD-CT data is provided at a diffraction spot size of 25 microns for three region of interest slices, with a dataset size of 40x2000x80. Both the raw and reconstructed data is provided, along with the code to perform the reconstructions. 

XRD-CT data is also provided at a diffraction spot size of 50 microns for a full 1.05mm volume, with a dataset size of 20x2000x40. Scans start at 43336 and finish at 43401, with a movement of 0.05mm vertically upwards between each scan. The raw and reconstructed data is provided, along with the code used to perform the reconstructions. Note: Scan 43401 is excluded as a phase-based reconstruction could not be performed.

Powder X-Ray Diffraction data can be found in an alternative repository at 10.5281/zenodo.13329670 which provides the q-values of the peaks for both the Zn and Na phase to allow the best reconstructions.

本仓库包含在钻石光源（Diamond Light Source）的双成像与衍射（Dual Imaging and Diffraction, DIAD / K11）装置上采集的掺锌13X沸石样品的X射线衍射计算机断层扫描（X-Ray Diffraction Computed Tomography, XRD-CT）数据。

该数据集提供了衍射光斑尺寸为25微米的三个感兴趣区域切片的XRD-CT数据，数据集维度为40×2000×80，同时包含原始数据与重建数据，以及用于执行重建的代码。

此外，本仓库还提供了衍射光斑尺寸为50微米的完整1.05毫米体积的XRD-CT数据，数据集维度为20×2000×40。扫描编号从43336起始，至43401结束，每次扫描间垂直向上移动0.05毫米。该部分同样包含原始数据与重建数据，以及用于执行重建的代码。注意：由于无法完成基于相位的重建，扫描编号43401被排除在外。

粉末X射线衍射数据可在另一个仓库中获取，其DOI为10.5281/zenodo.13329670，该仓库提供了锌相和钠相的衍射峰q值，以助力实现最优重建。
