Abstract

We present the design of COMIRA, a compact magnetic spectrometer for space radiation measurement. The spectrometer consists of four layers of scintillating fiber trackers, four layers of silicon strip trackers, one threshold Cherenkov counter, two anti-coincidence counters, and a permanent magnet. The detector has an overall dimension of approximately 12x12 cm3 and a geometrical acceptance of ~6.6 cm2sr. Based on combined measurements of charge, velocity, and rigidity (momentum/charge), it enables the simultaneous measurement of the energy spectrum, angular distribution and time evolution of individual radiation components, including electrons, positrons, protons and light nuclei over an energy range from tens of MeV to several GeV. The design can be further optimized depending on the available resources and constraints of the hosting space platform.
