“…For instance, the pre-amplifier developed in the framework of the PANDORA experiment achieves an energy resolution of 0.8 keV FWHM with a power consumption of 200 mW. This is much greater than the 10 mW power consumption of the integrated CSP designed for the N3G project [16].…”

The higher counting-rate and radiation hardness required by modern gamma spectroscopy experiments highlight the need for a new generation of High-Purity Germanium detectors based on electrons-collecting electrodes. To achieve this goal, new doping technologies are required. The one studied by the N3G (Next Generation Germanium Gamma detectors) project is the Pulsed Laser Melting. Besides the development of innovative segmented High-Purity Germanium crystals, the project is also aimed at developing a detector case complete of contact structures and front-end electronics. A specific integrated circuit pre-amplifier is being designed: a first version was tested at room temperature, using a pulser as pre-amplifier input. A resolution of 1.08 keV with 15 pF input capacitance, reproducing the one of a detector single segment, was obtained with 6 µs shaping time.

The PANDORA project aims to investigate, by a new experimental approach, the β-decays lifetimes of isotopes of nuclear astrophysics interest as a function of thermodynamic conditions of a laboratory plasma able to mimic some stellar-like conditions. A γ-ray detection system was designed by GEANT4 simulations to tag the in-plasma β-decays via the γ-rays emitted from the excited states of the daughter nuclei. The feasibility of PANDORA, in terms of significance levels, was checked by a “virtual experiment run”, also investigating the sensitivity for discriminating among different theoretical predictions.

“…the dynamical equilibrium can be reached under proper tuning conditions of the magnetic field profile, background pressure, and radiofrequency (RF) power. The b decay events will be tagged detecting the g-rays emitted by the daughter nuclei, still confined in the plasma, using an array of high efficiency High Purity Germanium (HPGe) detectors [10]. The inplasma measured radioactivity will be directly correlated to the plasma thermodynamical properties (density and temperature) which will be monitored on-line using a multidiagnostics setup.…”

Theoretical predictions as well as experiments performed at Storage Rings have shown that a high degree of ionization can affect the half-life of β-radionuclides. The PANDORA project aims at investigating,for the first time, beta decay rates in a plasma, simulating specific stellarlike conditions. A description of the physics motivations and the experimental setup developed to accomplish this task is given. The physics cases selected for the first experimental campaign are also presented.
