“…Consequent observations of several other novae (V1369 Cen, V5668 Sgr, V2944 Oph, V407 Lupi, V838 Her) also reveal the presence of 7 Be lines in their spectra. Meanwhile, there could be other sources of 6,7 Li. Low-energy measurements by PAMELA [59] show that 7 Li/ 6 Li≈1.1 below 1 GeV/n.…”

“…Today, this can be considered a very challenging goal, but not impossible. Meanwhile, several breakthrough experiments have been proposed, e.g., AMS-100 [5], HERD [6], HERO [7], ALADInO [8], which significantly extend capabilities of the current instrumentation. For example, AMS-100 is designed to have a geometrical acceptance of ∼100 m 2 sr.…”

The last two decades have brought spectacular advances in astrophysics of cosmic rays (CRs) and space-and ground-based astronomy. Launches of missions that employ forefront detector technologies enabled measurements with large effective areas, wide fields of view, and precision that we recently could not even dream of. Meanwhile, interpretation of the individual slices of information about the internal working of the Milky Way provided by such experiments poses challenges to the traditional astrophysical models. New mysteries arise in the composition and spectra of CR species at low and high energies, in the energy range where we thought the main features were already understood fairly well. This accumulation of unsolved puzzles highlights the peculiarity of the current epoch and means that major breakthroughs are still ahead. In my talk, I review the current state of direct measurements of CRs and discuss their possible interpretations. Unfortunately, many important ideas and publications are not discussed here due to the space limitations.

“…Blue and red dots represent, respectively, spectrometric and calorimetric instruments. The values reported in the picture are from [33] (CALET), [34,35] (DAMPE), [36][37][38][39] (AMS-02), [40] (HERD), [32] (AMS-100). The values of acceptance may depend on the analysis to which they are referred, and shall be considered as a benchmark value only.…”

A new generation magnetic spectrometer in space will open the opportunity to investigate the frontiers in direct high-energy cosmic ray measurements and to precisely measure the amount of the rare antimatter component in cosmic rays beyond the reach of current missions. We propose the concept for an Antimatter Large Acceptance Detector In Orbit (ALADInO), designed to take over the legacy of direct measurements of cosmic rays in space performed by PAMELA and AMS-02. ALADInO features technological solutions conceived to overcome the current limitations of magnetic spectrometers in space with a layout that provides an acceptance larger than 10 m2 sr. A superconducting magnet coupled to precision tracking and time-of-flight systems can provide the required matter–antimatter separation capabilities and rigidity measurement resolution with a Maximum Detectable Rigidity better than 20 TV. The inner 3D-imaging deep calorimeter, designed to maximize the isotropic acceptance of particles, allows for the measurement of cosmic rays up to PeV energies with accurate energy resolution to precisely measure features in the cosmic ray spectra. The operations of ALADInO in the Sun–Earth L2 Lagrangian point for at least 5 years would enable unique revolutionary observations with groundbreaking discovery potentials in the field of astroparticle physics by precision measurements of electrons, positrons, and antiprotons up to 10 TeV and of nuclear cosmic rays up to PeV energies, and by the possible unambiguous detection and measurement of low-energy antideuteron and antihelium components in cosmic rays.

“…Such an instrument was proposed but not selected for the GLAST mission [57]. Possible future missions based on scintillating fibers include the Advanced Particle-astrophysics Telescope (APT) [17], High Energy cosmic-Radiation Detection (HERD) facility [58], and Gamma-400 [75].…”

Electron-positron pair production is the essential process for high-energy γ-ray astrophysical observations. Following the pioneering OSO-3 counter telescope, the field evolved into use of particle tracking instruments, largely derived from highenergy physics detectors. Although many of the techniques were developed on balloon-borne γ-ray telescopes, the need to escape the high background in the atmosphere meant that the breakthrough discoveries came from the SAS-2 and COS-B satellites. The next major pair production success was EGRET on the Compton Gamma Ray Observatory, which provided the first all-sky map at energies above 100 MeV and found a variety of γ-ray sources, many of which were variable. The current generation of pair production telescopes, AGILE and Fermi LAT, have broadened high-energy γ-ray astrophysics with particular emphasis on multiwavelength and multimessenger studies. A variety of options remain open for future missions based on pair production with improved instrumental performance.
