AbstraktAbstract
Hybrid pixel detectors of Timepix technology have become increasingly interesting for space applications. Several devices are for example flown on the international space station providing a real-time measurement of the radiation levels. A key strength of Timepix is that ionizing particle interactions in the sensor are seen as imprints in the pixel matrix (tracks) with a rich set of features which can be exploited for the identification of impinging particles and particle trajectory reconstruction. The first Timepix (256 x 256 pixels, pixel pitch: 55 µm) used in open space is SATRAM (Space Application of Timepix Radiation Monitor) attached to the Proba-V satellite launched to low earth orbit (LEO) in 2013. In this contribution, measured dose, electron, and proton flux maps are shown. It is demonstrated how the use of machine learning tools improves particle separation. Further, the development and space qualification of a MIniaturized RAdiation Monitor (MIRAM) based on the latest-generation chip of the Timepix family, Timepix3, are described.
