“…The segmentation of this Active Detection Unit (ADU) given by the fibers allows us to record the energy-loss profile, and hence the change of the linear energy transfer (LET), along a particle's track through the detector. From this information, we can not only determine a particle's energy and the direction it came from but also establish its identity using a method called Bragg curve spectroscopy [18]. The particle identification is most precise for protons and light ions with energies that translate to a penetration depth that is shorter than or comparable to the size of the detector's active volume; it becomes increasingly imprecise for heavier nuclei and at higher energies.…”

“…The latter two aspects were the key enabling factors that made the development of RadMap's ADU possible. The omnidirectional sensitivity results in a geometrical acceptance of 1013 cm 2 sr if only a single fiber must be hit; to allow reconstruction of particle tracks, at least four fibers must produce a signal, resulting in a slightly lower acceptance of 925 cm 2 sr [18]. For high-energy particles passing through the detector, our track reconstruction…”

The RadMap Telescope is a new radiation-monitoring instrument operating in the U.S. Orbital Segment (USOS) of the International Space Station (ISS). The instrument was commissioned in May 2023 and will rotate through four locations inside American, European, and Japanese modules over a period of about six months. In some locations, it will take data alongside operational, validated detectors for a cross-check of measurements. RadMap's central detector is a finely segmented tracking calorimeter that records detailed depth-dose data relevant to studies of the radiation exposure of the ISS crew. It is also able to record particle-dependent energy spectra of cosmic-ray nuclei with energies up to several hundred MeV per nucleon. A unique feature of the detector is its ability to track nuclei with omnidirectional sensitivity at an angular resolution of two degrees. In this contribution, we present the design and capabilities of the RadMap Telescope and give an overview of the instrument's commissioning on the ISS.
