Description
The Alpha Magnetic Spectrometer (AMS) is a particle-physics experiment that measures cosmic ray components in low-earth orbit. With its permanent magnet and instrumentation, AMS analyzes cosmic rays across a rigidity range from 1 GV to several TVs. Since its installation on the International Space Station in 2011, AMS has been discerning antimatter from matter. It will continue to collect data until the station decommissioning scheduled for 2030.
By 2026, the collaboration will enhance the AMS silicon tracker with AMS-L0. This upgrade will increase by 300% the acceptance in many analysis channels while identifying nuclei before their fragmentation. AMS-L0 involves installing an additional tracking layer above the existing instrument to provide particle input coordinates and charge measurements over $4~m^2$.
The two silicon micro-strip planes that make up the layer are stacked back-to-back and arranged 45 degrees to each other. Each plane is divided into quarters with an active area of $1~m^2$.
We will briefly outline the design and construction of one of the AMS-L0 quarter planes. We will next delve into the characterization conducted by particle beam exposition of the single constructing element of AMS-L0. Finally, we will present the results of ions identification up to $Z=29$ (Nickel) and spatial resolution of $11~\mu m$.
