Conversion Mössbauer Spectrometer

Sample surface investigation

General information

Usage

  • Conversion geometry, the gamma radiation is impacting the sample, causing electrons emission, the detector is counting electrons and collecting emission spectrum.
  • The sample is placed inside of the detection chambre
  • Complete system can be operated remotely (requires internet connection for control PC), excluding gas flow (manual control)
  • Requires cylinder with counting gas (consumable)

Sample types

  • Thick bulk samples (up to 2 mm)
  • Thin layers (from 50 nm)
  • Sample size limited to 10 mm diameter

Technical Specifications
