• Crystal Structure

  Structure:

  Chose crystal structure. This version supports 4 structures, Simple Cubic, Face Centered Cubic, Body Centered Cubic, and Diamond Structure.

  Lattice Constant:

  Enter lattice constant. The default value is that for Silicon.

  Inner Potential:

  Enter effective inner potential near the surface. The potential affects refractive effect for outgoing electron. The default value is that for Silicon.

• Surface

  Index:

  Enter surface index. Integer from -99 to 99 is available.

• Incident Electron

  Azimuth:

  Enter azimuth index of incident electron. Integer from -99 to 99 is available.

  Azimuth Off Angle:

  Enter off azimuth angle from the above azimuth index.

  Glancing Angle:

  Enter glancing angle of incident electron.

  Electron Energy:

  Enter incident electron energy in KeV.

• Drawing

  Camera Length:

  Enter camera length in mm.

  Index Range:

  Enter calculation range from 1 to 99.

  h+k+l >:

  Enter limit of sum of index numbers. If you set 4 for Index Range and 10 for the Limit, (443), (444) etc. will be ignored. Integer from 3 to 100 is available.

  Resolution:

  Enter calculation unit of angle. This corresponds to angle resolution around the Kossel Cone. You'd better increase the application memory when you decrease this value.

  Ignore Kinematical Extinction Law:

  Check this to ignore kinematical extinction, which means that diamond structure is the same as fcc.

  Suppress Defect Lines:

  Check this to hide defect Kikuchi lines. However, calculation itself is the same and TEXT save always includes defect lines.

  Mark Specular Spot Position:

  Check this to mark specular spot position.

  Show Line Indexes:

  Check this to show line indexes.

  Show Parameters:

  Check this to show parameters in the result window.
