Abstract A computer program for 2-d electron diffraction pattern simulation has been developed under the DEC Micro-VAX II/Micro-VMS environment. Diffraction patterns or images formed by focusing an electron beam of arbitrary energy on a sample can be simulated. The 3-d sample structure can be either pre-calculated or on-line generated based on the symmetry and other necessary information provided by the user. The output is a series of diffraction patterns or images, at the user's ch... Title of program: MIDS Catalogue Id: ABLK_v1_0 Nature of problem To simulate the 2-d convergent beam electron diffraction(CBED) patterns produced by focusing a coherent beam, such as that from a field emission gun, on a crystal or defective sample for structure study at the atomic level. The simulation helps researchers to understand various electron diffraction phenomena observed experimentally and to predict new ones. Versions of this program held in the CPC repository in Mendeley Data ABLK_v1_0; MIDS; 10.1016/0010-4655(90)90189-8 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
