Abstract

We discuss a simple magnetic spectrometer to be installed on a satellite or space station. The purpose of this spectrometer is to search for primordial antimatter to the level of antimatter/matter ≈10⁻⁹, improving the existing limits obtained with balloon flights by a factor of 10⁴ to 10⁵. The design of the spectrometer is based on an iron-free, NdFeB permanent magnet, scintillation counters, drift tubes, and silicon or time projection chambers. Different design options are discussed. Typically, the spectrometer has a weight of about 2 tons and an acceptance of about 1.0 m² sr. The availability of the new NdFeB material makes it possible for the first time to put a magnet into space economically and reliably.

Explanation of nearby SNRs for primary electron excess and proton spectral bump
2022, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Several groups have reported a possible excess of primary electrons at high energies with the joint fit of the positron fraction and total electron/positron spectra. With the latest release of high-precision electron/positron spectra measured by AMS-02, we further confirm this excess by fitting ΔΦ (i.e., $Φ_{e^{-}} - Φ_{e^{+}}$ ) data in this work. Then we investigate the contribution of a single nearby supernova remnant to the primary electron excess and find that Monogem can reasonably account for this excess. Moreover, we predict that the electron spectrum may harden again at a few TeVs due to Vela's contribution. DAMPE, which can accurately measure electrons at TeV scale, is expected to provide the robust test of this new spectral feature in the near future. Finally, we fit the proton spectrum data of DAMPE with Monogem or Loop I. We find that both the primary electron excess and the proton spectral bump could be mainly generated by Monogem.
AMS-100: The next generation magnetic spectrometer in space – An international science platform for physics and astrophysics at Lagrange point 2

Many demanding technical questions need to be worked out in detail to make such a large space mission possible. These questions are of similar complexity as the ones that had to be solved to realize AMS-02 after the proposal in 1994 [122]. The AMS-100 concept as outlined in this article (Table 5) has the potential to improve the sensitivity of AMS-02 by a factor of 1000.
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.
Silicon strip and pixel detectors for particle physics experiments
2019, Physics Reports
Following a brief introduction to the roles that a tracking detector fulfills in a particle physics experiment, the concept of a silicon tracking detector is introduced. The contributors to position resolution of the detector are described along with some technological developments that have occurred in response to them. An overview of the historical evolution of the silicon detector concept follows, with emphasis on what was learned at significant junctures. A light reminder of foundational concepts related to semiconductors and $p$ - $n$ junctions is provided, in order to motivate various choices that have been made in the implementation of sensor geometries; advantages and disadvantages of some key implementations are mentioned. The characteristics of an operating detector are described, as are the typical experimental goals that influence decisions on detector optimization. Due to its pervasive effect on nearly all detector characteristics, the mechanisms and vocabulary of radiation damage are introduced. Features of the classic silicon detector design that have been developed to mitigate that damage are described, and the evolution of the design toward higher radiation tolerance is indicated. The concept of the module is introduced, for strip detectors and pixel detectors. Design considerations for detector cooling, interconnections, power distribution, and support are mentioned. Various approaches to monolithic pixel detectors are described and contrasted with hybrid detectors. A look at the research frontier leads to low gain avalanche detectors and small-cell 3D detectors.

For example, the precision measurement of the mass difference between nuclei and anti-nuclei can test the fundamental CPT theorem for systems bound by the strong interaction [15]. The measured production rate of light anti-nuclei in heavy-ion collisions provides a point of reference for possible future observations in cosmic radiation for the motivation of hunting for antimatter and dark matter in the Universe [16–19]. The antimatter nuclei production provides the possibility to test the interactions between antimatter and antimatter [20].
Combining the covariant coalescence model and a blast-wave-like analytical parametrization for (anti-)nucleon phase–space freezeout configuration, we explore light (anti-)nucleus production in central Au+Au collisions at $\sqrt{s_{NN}} = 200 GeV$ . Using the nucleon freezeout configuration (denoted by FO1) determined from the measured spectra of protons (p), deutrons (d) and ³He, we find the predicted yield of ⁴He is significantly smaller than the experimental data. We show this disagreement can be removed by using a nucleon freezeout configuration (denoted by FO2) in which the nucleons are assumed to freeze out earlier than those in FO1 to effectively consider the effect of large binding energy value of ⁴He. Assuming the binding energy effect also exists for the production of ⁵Li, ${}^{5}{\overline{Li}}$ , ⁶Li and ${}^{6}{\overline{Li}}$ due to their similar binding energy values as ⁴He, we find the yields of these heavier (anti-)nuclei can be enhanced by a factor of about one order, implying that although the stable (anti-)⁶Li nucleus is unlikely to be observed, the unstable (anti-)⁵Li nucleus could be produced in observable abundance in Au+Au collisions at $\sqrt{s_{NN}} = 200 GeV$ where it may be identified through the p–⁴He ( $\overline{p}$ – ${}^{4}{\overline{He}}$ ) invariant mass spectrum. The future experimental measurement on (anti-)⁵Li would be very useful to understand the production mechanism of heavier antimatter.
Upgrade of the Alpha Magnetic Spectrometer (AMS-02) for long term operation on the International Space Station (ISS)

The Alpha Magnetic Spectrometer AMS-01 [1,2] was flown as an engineering, precursor flight on the space shuttle Discovery (mission STS-91, June 1998).
Following the decision to maintain the International Space Station (ISS) on orbit until at least 2020 (possibly until 2028) the AMS collaboration decided to correspondingly extend the lifetime of the experiment. Since the limited amount of helium used to cool the superconducting magnet allowed for only a limited run time of the experiment, a change from the superconducting magnet to the permanent magnet used in AMS-01 became necessary. Due to the lower magnetic field, to maintain the resolution the silicon tracker also had to be reconfigured with the installation of a silicon plane on the top of the experiment and a new plane above the electromagnetic calorimeter.
The scintillator detector for the fast trigger and time-of-flight (TOF) measurement of the space experiment AMS-02
2010, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
The “Time-Of-Flight” (TOF) system of the AMS-02 superconducting spectrometer, to be installed in the ISS International Space Station, consists of four layers of plastic scintillation counters. During the precursor mission AMS-01 (June 1998), a similar system successfully operated in space for 10 days. However, the AMS-02 TOF had to be redesigned taking into account the more stringent mass and power constraints of the AMS-02 detector. The main characteristics of the new TOF system are (a) capability to stand the high fringing field of AMS-02 superconducting magnet; (b) high redundancy of electronic components for unmanned operation of at least three years in the space station; (c) capability to operate in the space environment on the ISS. Counters and electronics have been extensively tested before the installation in the spectrometer.
