AMS-100: The next generation magnetic spectrometer in space – An international science platform for physics and astrophysics at Lagrange point 2

Abstract

The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of 100 m 2 sr and to be operated for at least ten years at the Sun-Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic rays, and in particular in cosmic antimatter, by at least a factor of 1000. The magnet design is based on high temperature superconductor tapes, which allow the construction of a thin solenoid with a homogeneous magnetic field of 1 Tesla inside. The inner volume is instrumented with a silicon tracker reaching a maximum detectable rigidity of 100 TV and a calorimeter system that is 70 radiation lengths deep, equivalent to four nuclear interaction lengths, which extends the energy reach for cosmic-ray nuclei up to the PeV scale, i.e. beyond the cosmic-ray knee. Covering most of the sky continuously, AMS-100 will detect high-energy gamma rays in the calorimeter system and by pair conversion in the thin solenoid, reconstructed with excellent angular resolution in the silicon tracker.

Galactic halo size in the light of recent AMS-02 data

“…CR projects like HERD (Cattaneo & HERD Collaboration 2019), ALADInO (Adriani et al 2019), or AMS-100 (Schael et al 2019). In any case, be it for Be/B or isotopic ratios, the common limiting factor to all improvements are cross-section uncertainties.…”

Deciphering the Local Interstellar Spectra of Secondary Nuclei with the Galprop/Helmod Framework and a Hint for Primary Lithium in Cosmic Rays

“…However, isotopic abundances are very difficult to measure at high energies and would require a large magnetic spectrometer with a superconducting magnet in space. The outlines of such future instruments are currently discussed in the literature (Schael et al 2019), but building and launching them into space may take a couple of decades. We, therefore, should concentrate on elimination of other possibilities through new measurements of the production cross sections or reevaluation of the available data.…”

Advantages and Requirements in Time Resolving Tracking for Astroparticle Experiments in Space

“…Cosmic Rays (CR) are messengers from the universe that, with the recent opportunity to operate precision particle physics detectors in space, stand as major probes to investigate astrophysical processes (with both Charged CR (CCR) [1,2] and photons at all wavelengths: radio [3,4], microwaves [5][6][7][8], IR and sub-mm [9][10][11][12][13], optical and UV [14][15][16][17], X-rays [18][19][20], γ-rays (GR) [20][21][22]) and also fundamental physics (Dark Matter [23][24][25][26], Gravitational Waves [27], Antimatter Asymmetry [28][29][30], Cosmology [31]), producing unique and complementary information to what is provided by experiments in laboratories at ground.…”

“…Future experiments aiming to reach higher energies and improved sensitivities will need to cover larger surfaces with Si detectors, with a substantial increase in the number of readout channels (e.g., e-ASTROGAM [36], AMEGO [37], PANGU [38], HERD [39], ALADInO [29], AMS-100 [30]). An increase in the total area of the Si detectors results in a direct increase in the number of electronics channels.…”
