Fundamental Physics with antimatter:

  • Atomic physics with positronium (Ps), the bound state of a positron and an electron.
  • Study of gravity acting on antihydrogen, positronium and protonium. 
  • Positronium laser spectroscopy and positronium laser cooling.
  • Production of positron/positronium converters
  • Development of laser for positronium manipulation in selected quantum states.
  • Development of positron bunched beams.
  • Development of a beam of metastable positronium (long lived positronium) 
  • Study and development of position sensing detectors for charge particle and gamma rays with energy up to 511 keV.
  • Study for the production of polarized positronium into vacuum.
  • Study of the entanglement of gamma photons

Solid state Physics with antimatter

  • Study and characterization of porosity, through detection of positronium formation (3 gammas PAS, Positron Annihilation Spectroscopy; PALS: Positron annihilation lifetime spectrosopy), in polymeric and biopolymer nanocomposite thin films for the realization of low permeability molecular and dielectric sieves.
  • Characterization of the chemical surrounding of porosity, cavities and point defects by the CDBS (Coincidence Doppler Broadening Spectroscopy) technique.
  • Depth profiling of vacancy like defects in oxide by DBS (Doppler Broadening Spectroscopy) and PALS.

Technology transfer

  • Development of parabolic solar concentrators for alternative energy
