“…Emission is expected [68,72] from positron-electron annihilation (e + being emitted by the β + -unstable shortlived isotopes 13 N and 18 F), and from the decay of the medium-lived isotopes 22 Na, which is produced in ONe novae, and 7 Be, produced in CO novae. The first type of emission consists of a 511 keV line plus a continuum between about 20 and 511 keV, whereas the second, longlasting emission consists of two γ-ray lines at 1275 keV ( 22 Na) and 478 keV ( 7 Be).…”

e-ASTROGAM ('enhanced ASTROGAM') is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated to the study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV -the lower energy limit can be pushed to energies as low as 150 keV, albeit with rapidly degrading angular resolution, for the tracker, and to 30 keV for calorimetric detection. The mission is based on an advanced space-proven detector technology, with unprecedented sensitivity, angular and energy resolution, combined with polarimetric capability. Thanks to its performance in the MeV-GeV domain, substantially improving its predecessors, e-ASTROGAM will open a new window on the non-thermal Universe, making pioneering observations of the most powerful Galactic and extragalactic sources, elucidating the nature of their relativistic outflows and their effects on the surroundings. With a line sensitivity in the MeV energy range one to two orders of magnitude better than previous generation instruments, e-ASTROGAM will determine the origin of key isotopes fundamental for the understanding of supernova explosion and the chemical evolution of our Galaxy. The mission will provide unique data of significant interest to a broad astronomical community, complementary to powerful observatories such as LIGO-Virgo-GEO600-KAGRA, SKA, ALMA, E-ELT, TMT, LSST, JWST, Athena, CTA, IceCube, KM3NeT, and the promise of eLISA.

“…Moreover, four DSSSDs (Double Sided Silicon Strip Detector) [12] were placed in the beam line, two in front of and two behind the reaction target, to measure the track of the impinging particles and of the charged reaction products leaving the target. A valid signal in all four DSSSDs is required for further analysis (see section III A).…”

Neutron-rich light nuclei and their reactions play an important role for the creation of chemical elements. Here, data from a Coulomb dissociation experiment on 20,21 N are reported. Relativistic 20,21 N ions impinged on a lead target and the Coulomb dissociation cross section was determined in a kinematically complete experiment. Using the detailed balance theorem, the 19 N(n, γ) 20 N and 20 N(n, γ) 21 N excitation functions and thermonuclear reaction rates have been determined. The 19 N(n, γ) 20 N rate is up to a factor of 5 higher at T < 1 GK with respect to previous theoretical calculations, leading to a 10 % decrease in the predicted fluorine abundance.

“…Simultaneous measurement of position and energy loss in silicon are performed along the charged particle trajectory in each layer, with a 10 μm spatial resolution for singly charged particles, going down to ∼ 6 μm for Z>1. The low noise and wide dynamic range of the silicon readout electronics allow to exploit the energy loss measurements to determine the particle absolute charge for nuclei up to iron [15]. The rigidity and the charge sign are measured up to 2 TV, with a resolution σR/R ∼ 2.5% up to O(100) GV;…”

Abstract. AMS-02 is a multipurpose magnetic spectrometer that will operate on the International Space Station for at least two decades. The detector is designed to measure with very high accuracy the composition of cosmic rays near Earth. With a large acceptance, an intense magnetic field from a permanent magnet and a very efficient particle identification, AMS-02 will provide the highest precision to date in cosmic rays measurements up to the TeV region, achieving a sensitivity to the existence of primordial antimatter in the cosmic rays of one part in a billion, and providing the most complete information on the indirect observation of dark matter. During the first year in space, several billion events have been recorded. The flight operation, the detector performance, together with early results and perspective for physics measurements are reported.
