Measuring Cosmic Rays with the RadMap Telescope on the International Space Station
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
