Reference books on electron diffraction include "Easy Electron Diffraction and Elementary Crystallography-Indexing of Electron Diffraction Figures" [Kyoritsu Shuppan, by Tanaka, Terauchi, and Tsuda], and "Surface / Interface Physics" on RHEED [Maruzen, Sone. Hen (new development of series physical physics)] etc. ※ Operating environment This software is CPU: 68020 and above (should not have FPU), PowerPC series Operating System: Mac OS 7.5 or higher (Thread Manager required) Works with. It's a Fat Binary, so it works best on both 68K Macintosh and Power Macintosh. He has developed it on 9500/200 and 7600/200 (both Mac OS 8J), and has confirmed the operation on 7100/120 (Mac OS 7.5.3J), but confirmed the operation on 68K Macintosh. Not available. It may also work on System 7.1, but I haven't confirmed it. Please see here for an example of the execution result (24KB). * Download rconv101.sit.hqx (program: 600KB) rconv_source.sit.hqx (source file: 1.2MB) ※ how to use 1. When started, a dialog will appear requesting a PICT file for the RHEED pattern to be converted. The image format is PICT only. Also, the converted image is forcibly converted to 256 gray. 2. When you specify a file, separate windows appear at the top and bottom, and the original RHEED pattern is displayed in the upper area. The two circles and one line in this represent the specular reflection spot (green circle), the direct spot (red circle), and the shadow edge (blue line), respectively. Drag with the mouse so that these three markers match the RHEED pattern. Note that the shadow edge always maintains the relationship between the perpendicular bisectors of the two spots, so moving one will automatically adjust the other markers to meet this requirement. 3. After adjusting the position of the marker, enter the field of camera length or electron beam viewing angle above. The unit of camera length is pixel, and the unit of viewing angle is °. The distance D between the two spots specified above is always in the relationship of tan θ = D / 2L (θ: viewing angle, L: camera length), so if you enter one, the other will be calculated automatically. First of all, it is convenient to find the camera length using a photo with a known viewing angle. The last used camera length will be automatically adopted at the next startup. 4. After specifying the marker a…
