We use novel ionizing radiation imaging approach for resolving CRII rate and also testing the feasibility of completely new low-cost and potentially accurate approach to measuring the ambient environment ion concentration - by dependence of breakdown voltage in custom designed spark tube. As demonstrated previously on TimePiX@Space, BEXUS is ideal platform for the proposed, extended in-situ measurements. Not only because of the altitudes reached, but also thanks to its slow ascend velocity (and though statistically significant and reasonably balanced-conditions sampling) of the arctic upper troposphere and stratosphere, which are of specific study interest. Also the possibility of studies of effects observable well only at high cutoff-rigidities, associated with high-geomagnetic latitude, proves ESRANGE as the ideal place for such observation.
This project could serve also as testbed contributing to the ESA action in the area of Space Situational Awareness, studying feasibility of specific detector application for multi-point space-based monitoring. It could detect anisotropy of Galactic Cosmic Ray intensity caused by approach of dangerous plasma clouds from coronal mass ejections on the Sun if deployed ultimately in network, piggybacking various satellites.
