The I.P.N.E. is the Experimental Nuclear Physics
Institute of the University of Liège. Its main goals are the investigation
of multi-charged ions (beam-foil
spectroscopy) and the development of analytical
techniques based on accelerated charged particles.
The beam-foil spectroscopy consists to send
a beam of high velocity particles produced by an accelerator through a carbon
foil. The beam is ionised and excited by its interactions with the foil
atoms. Excited ion energies and atomic life-times can be deduced from the
electromagnetic radiation emitted by the ions as they return to their ground
state. In laser-beam-foil spectroscopy, the
excitation in the foil is followed by a selective populating of levels obtained
by using a continuous dye laser.
The analytical techniques allow the determination
of major and trace elemental composition in various kinds of samples. The
methods used to perform these analyses are:
The aforementionned methods are well adapted to aplications, studies,
and surveys in such diverse fields as medicine, biology, environmental studies,
volcanology, archaeology or geology. Methodological studies are also undertaken,
notably the development of methods and computer programs for the microanalysis
and construction of electronic interface apparatuses.
A wide range of experimental apparatus is used
to perform the described research.
