The PANDORA project: Plasmas for Astrophysics, Nuclear Decays Observation and Radiation for Archaeometry

Speaker: David Mascali (INFN, Laboratori Nazionali del Sud, Catania)

Date and time: 2017-05-24 12:30

PANDORA is planned as a new facility based on a state-of-the-art plasma trap confining energetic plasma for performing interdisciplinary research in the fields of Nuclear Astrophysics, Astrophysics, Plasma Physics and Applications in Material Science and Archaeometry. The plasmas become the environment for measuring, for the first time, nuclear decays rates in stellar-like condition (such as 7Be decay and beta-decay involved in s-process nucleosynthesis), especially as a function of the ionization state of the plasma ions. These studies will give important contributions for addressing several astrophysical issues in both stellar and primordial nucleosynthesis environment (e.g. determination of solar neutrino flux and 7Li Cosmological Problem), moreover the conned energetic plasma will be a unique light source for high performance stellar spectroscopy measurements in the visible, UV and X-ray domains, offering advancements in observational astronomy. As to magnetic fields, the experimental validation of theoretical first and second order Lande factors will drive the layout of next generation polarimetric units for the high resolution spectrograph of the future giant telescopes. Finally, PANDORA will be suitable for energy conversion, making the plasma a source of high intensity electromagnetic radiation, for applications in Material Science and Archaeometry.
