Giovanna Simeoni

1st instrument scientist, responsible for the time-of-flight spectrometer TOFTOF

Can you tell us a bit about your studies and your scientific field?

Past/present scientific fields of interest:

  • disordered systems, amorphous materials, glass physics
  • nanoparticles and nanostructures
  • supercritical fluids
  • multiferroics

Experimental techniques:
inelastic light scattering (Brillouin, Raman, X-ray), inelastic neutron scattering, and high pressure cells

Instrumental skills:

  • installation of a tandem-multipass Fabry-Perot interferometer “Sandercock” (2005 -Laboratoire de Physico-Chemie des Materiaux Luminescents, Universite´ Claude Bernard, Lyon 1)
  • installation of a grating monochromator “Sopra” DMDP 2000 (2006 – Dipartimento di Fisica, Universita´ “La Sapienza”, Roma)
  • upgrade of the time-of-flight spectrometer TOFTOF (2011- FRM II)

What´s your background in neutron scattering?

Two years of Post-Doc at the time-of-flight Spectrometer TOFTOF (FRM II)
