Design Overview of the Segmented Scintillation Detector "RUBIK" for Space Radiation Monitoring — •Roman Bergert, Hans-Georg Zaunick, and Kai-Thomas Brinkmann — Institute of Experimental Physics II, Justus Liebig University Giessen
A segmented particle tracking detector for space applications, named RUBIK, will be presented. The detector utilizes 125 individual PVT-based scintillator cubes (1 x 1 x 1 cm3) as the sensitive volume, providing compactness and high efficiency. This scintillation detector array is based on custom-developed front-end readout electronics, utilizing commercial off-the-shelf components, and is specifically designed to meet the stringent power consumption, size, weight and environmental requirements of the ROMEO space mission by the Institute of Space Systems at the University of Stuttgart.
The primary objective of RUBIK is to measure fluences and dose rates of charged particles with energies above 100 MeV, while determining their momentum vectors and providing precise event timing. This functionality has been tested under proton beam and laboratory conditions.
The overview will cover the current design concept, including signal processing schematics, as well as the mechanical and electronic layout. The performance of the detector will be evaluated in the context of mission-specific parameters, with a focus on hardware capabilities and the ability of the readout electronics to meet the required performance thresholds.
