Electron Flight
Simulator, version E contains all the standard features of Electron Flight
Simulator plus the ability to see beam scatter in an environmental or low-vacuum
SEM. When a gas is introduced into the chamber of an environmental or low-vacuum
SEM, the gas molecules cause the beam to scatter. The higher the chamber
pressure or the longer the working distance, the more the electron beam will
scatter. This scattering generates X-rays away from the original beam spot,
producing errors in the analysis. Electron Flight Simulator, version E lets you
vary the chamber pressure, gas type, accelerating voltage, and working distance
to correct for this scattering.
