SEM quiz

What is the main power source for SEM?

• Electrons

• Laser

• Light

• Radiation

Which main component creates Raster patterns?

• Magnetic Lens

• Scanning Coil

• Electron Beam

• Backscattered electron detector

What energy outputs are being produced by the electron Beam?(More than one Answer)

• secondary

  Backscattered electrons

• x-rays

• Auger Electrons

• Primary Backscattered electrons

• secondary Electrons

Auger electrons are:

• Low energy electrons that are being emitted by radionuclides

• High energy electrons that are being emitted by radionuclides

• electrons generated by inelastic interactions

• electrons generated by elastic interactions

Why is the secondary electron detector different from the Scanning coils?

• Creates Topographic map and scanning coils creates Rectangular images

• creates Rectangular images and scanning coils makes topographic map

The Optical microscope Uses:

• Visible light

• Magnetic Lens

• Electrons

• optical lens
