This electron source provides a high beam current at low beam energies, which makes it the ideal source for charge compensation, typically needed for XPS on charging samples.

Key features

  • Energy range 1 eV – 100 eV
  • Beam current (max.) 20 μA
  • Beam size (min.) 10-20 mm at max energy and 40 mm working distance


  • Computer control (optional)
  • Magnetic shielding (optional)
  • Remote control
Not all parameters can be reached simultaneously. Above specifications may change without notice.
