Natrolite The following submission contains the data collection and processing of datasets for the sample epidote under the NanEd round-robin project. A single crystal was identified, and precession data acquisition techniques were used to collect datasets on the same crystal. All the data sets were processed with PETS2 software. The table below summarizes the data collection parameters for the data sets. The following data is also included as a text file in the data folder. Precession: General information: Project NanED (www.naned.eu) ESR Project ESR12 - Round Robin Project Label RR1 Sample Label RR1-S2 Data set Label RR1-sample2-PEDT Instrumental: Instrument Transmission electron microscope Jeol F200 Radiation source Cold FEG Accelerating voltage 200 kV Wavelength 0.0251 Å Probe Type Microdiffraction Beam Diameter 75nm Beam Convergence Parallel beam, convergence <0.1mrad Detector Hybrid pixel detector ASI Cheetah M3 (bottom mounted) Number of pixels in the image 512 x 512 Pixel size 55 µm x 55 µm Effective camera length 250 mm Calibration constant 0.005835 Å-1/pixel Sample description: Name Natrolite Chemical composition Na2Si3Al2O10.(H2O)2 Sample source Sample preparation Powder crushed in a mortar and dispersed in n-butanol, drop deposited on a Cu grid with holey C film Experimental: Data Type Electron diffraction data - 3D ED Data collection method Precession Temperature (K) used during data collection 293 K Number of crystals contributing to the data set 1 Number of experimental frames 109 tilt range, tilt step, tilt per frame -49° to +59°, 1°, 0° Precession angle 1.35° Exposure time per frame 500ms Software: Software used for the data collection Instamatic software Software used for processing PETS2 (ver 2.1.20211012.1037) Authorship and bibliography Author(s) of the data Sara Passuti (ESR12) Related data Publication(s) Files and data formats Image folder tiff : Folder containing images of the diffraction pattern from each frames.
