Domain, Specialties : Physique nucléaire
Keywords:
Nuclear structure and spectroscopy, Gamma-ray Tracking
Research Unit : DPhN / LENA
Summary
The internship aims at future PhD students of the nuclear spectroscopy group at SPhN. It will allow the PhD candidate to familiarise him/herself with modern methods of nuclear spectroscopy and in particular the gamma-ray tracking used with the AGATA spectrometer currently being operated at the Legnaro National Laboratories (LNL, Italy).
Full description
The detection of gamma-rays, high-energy photons emitted in the de-excitation process of excited nuclei, informs us about the structure of atomic nuclei. Modern high-resolution gamma-ray spectrometers are built from Germanium semi-conductor detectors due to their excellent energy resolution and the fact that rather large crystals can be grown. AGATA is the latest gamma-ray spectrometer of the European high-resoltion spectroscopy community and will consist of 180 high-purity Germanium crystals. AGATA is based on the novel technique of gamma-ray tracking, whereby all interactions of each photon are registered due to the segmentation of the crystal surfaces and an analysis of the registered pulse shapes. This allows to reconstitute the path of each gamma-ray in the spectrometer.
The LENA laboratory of the nuclear physics department as well as the technical divisions of IRFU are strongly involved in the construction and exploitation of AGATA. Since 2021 AGATA is installed at the Legnaro National Laboratories (LNL, Italy) and where the group has realised several experiments. The candidate will familiarise him/herself with the experimental technique, the analysis tools and the simulation package before being able to analyse a part of the experimental data taken in Coulomb excitation of 232Th. Depending of the length of the internship and the planning at LNL facility the candidate will be able to participate in one of the upcoming experiments. The internship could also lead to a PhD thesis proposed by the group, in particular the one related to Coulomb excitation of exotic nuclei (see link above).
