Radiation noise and Total Ionizing Dose (TID) are very serious issues for any instrument proposed to missions that operate in intense radiation environments like JUICE or RBSP. Here we discuss issues and mitigation techniques related to penetrating particle background noise in particle sensors with illustrations taken from real spacecraft measurements. Whereas passive shielding can efficiently...

In this paper a setup is described, that will be used for an experimental verification of the small angle scattering rate of soft protons (~100 keV - 1 MeV) off of mirror shells of space telescopes with focusing optics. On existing missions (e.g. Chandra, XMM-Newton), the measured rate is a factor 3-4 higher than the predictions using multiple Rutherford scattering suggest. Two physical...

The exposure to high charge and energy (HZE) particles is one of major concerns for humans during their missions in space. Microdosimetry is a valuable tool for characterization of radiation quality. Measurements with Tissue-Equivalent Proportional Counters (TEPC) have been performed for several years in space for investigation of solar particle events and galactic cosmic-rays. The response...
