Nuclear Physics Experiments at Institut Laue-Langevin

by Ulli Koester (ILL Grenoble)

Friday, 22 March 2019 from to (Europe/Bucharest)
at DFN Seminar Room
Description
Institut Laue-Langevin (ILL) in Grenoble (France) is an international user
facility that exploits a high flux reactor as powerful neutron source.
Most of the about 40 instruments served by these intense neutron beams
exploit neutron scattering for studying questions in condensed matter
physics, chemistry, biology, materials science, etc.
However, there are also some unique instruments serving nuclear physics.

The recoil separator LOHENGRIN is used for high resolution fission studies
and nuclear spectroscopy of neutron-rich nuclides, the crystal
spectrometer GAMS enables gamma ray spectroscopy with ultrahigh (ppm)
energy resolution and the new FIPPS instrument serves for prompt gg and
ggg spectroscopy with (n,g) and (n,f) reactions.
Experiments on (n,p) and (n,a) reactions and fission are also performed at
the multi-purpose beam PF1b.

Moreover, high flux irradiation positions (neutron flux up to 1.5 1015
n.cm-2s-1) are used to produce radioisotopes with high specific activity
for medical applications and fundamental research.

Examples of recent and future applications of these instruments will be
discussed.
