| Resumen : | In this work we describe the design and construction of a Mössbauer spectrometer based in the use of a Channel Electron
Multiplier to detect the electrons emitted as a consequence of the resonant nuclear absorption of γ-Rays by 57Fe containing
samples. The main resonant signals being detected are the Fe(K), Fe(L) and Fe(M) conversion electrons as well as the
Fe(KLM), Fe(KLL) and Fe(LMM) Auger electrons. The design is compact since all the components of the spectrometer
are mounted into a single flange, so it can be easily installed in any conventional vacuum chamber dedicated to the study of
surfaces. Its performance was tested by acquiring Mössbauer spectra from a pure iron metal sheet and from an iron metal
thin film deposited onto a stainless steel plate. |
