Multimessenger astrophysics is based on the detection, with the highest possible accuracy, of the cosmic radiation. During the last 20 years, the advent space-borne magnetic spectrometers in space (AMS-01, Pamela, AMS-02), able to measure the charged cosmic radiation separating matter from antimatter, and to provide accurate measurement of the rarest components of Cosmic Rays (CRs) to the highest possible energies, have become possible, together with the ultra-precise measurement of ordinary CRs. These developments started the era of precision Cosmic Ray physics providing access to a rich program of high-energy astrophysics addressing fundamental questions like matter-antimatter asymmetry, indirect detection for Dark Matter and the detailed study of origin, acceleration and propagation of CRs and their interactions with the interstellar medium.

In this paper we address the above-mentioned scientific questions, in the context of a second generation, large acceptance, superconducting magnetic spectrometer proposed as mission in the context of the European Space Agency’s Voyage2050 long-term plan: the Antimatter Large Acceptance Detector In Orbit (ALADInO) would extend by about two orders of magnitude in energy and flux sensitivity the separation between charged particles/anti-particles, making it uniquely suited for addressing and potentially solving some of the most puzzling issues of modern cosmology.

Multimessenger天体物理学基于对宇宙辐射的检测，其准确性最高。在过去的20年中，太空中出现的星载电磁光谱仪（AMS-01，Pamela，AMS-02）能够测量带电的宇宙射线将反物质分离出来，并提供对宇宙中最稀有成分的准确测量尽可能高的能量射线（CR），以及对普通CR的超精确测量，已经成为可能。这些发展开创了精密宇宙射线物理学的时代，使人们能够访问丰富的高能天文学程序，以解决诸如物抗反对称性，暗物质的间接检测以及CR的​​起源，加速和传播及其相互作用的详细研究等基本问题。与星际介质。

在本文中，我们将在欧洲航天局Voyage2050长期计划的背景下提出的第二代大型接受超导磁谱仪中解决上述科学问题：轨道上的反物质大接受检测器（ALADInO）在能量和通量敏感性方面将带电粒子/反粒子之间的距离扩大大约两个数量级，使其特别适用于解决和潜在解决现代宇宙学中一些最令人困惑的问题。
