Description
This contribution discussed the space radiation environments in near earth orbits and the development of radiation detectors based on Timepix-technology for radiation dosimetry and radiation field decomposition.
Profiting from their single-layer particle discrimination, Timepix-type detectors provide science-class data capability with a large field of view at an order of magnitude lower weight and approximately half of the power consumption compared with commonly used space radiation monitors. Based on results achieved with the first Timepix-technology detector in open space, “SATRAM” (Space Application of Timepix Radiation Monitor) launched to 820 km LEO in 2013, I will outline the detector technology’s strengths and current limitations for remote operation in space. The development of next-generation space radiation monitors based on Timepix3 is then discussed, together with first results from ongoing space missions.
I will further shortly introduce a penetrating particle analyzer concept aimed at a precise measurement of the cosmic ray flux, composition, spectral characteristics and directions for in-situ measurement in deep space (pixPAN). This instrument is currently considered for a mission in a lunar orbit.
