The newly established group in ‘Applied High-Energy Heliophysics’ atUniversity of Applied Sciences Northwestern Switzerland (FHNW) proposesfor funding to support a series of observations of the Sun in the 5-80 keVX-ray band using the Nuclear Spectroscopic Telescope ARray (NuSTAR)satellite, a NASA small Explorer whose primary mission is in astrophysics. Designed with true focusing optics for extremely high sensitivity, NuSTARis an astrophysical observatory, but unlike virtually every otherhigh-energy astrophysics mission to date, it is capable of being pointedat the Sun. NuSTAR will observe the Sun with a sensitivity over 200 timesbetter than that of the Reuven Ramaty High Energy Solar SpectroscopicImager (RHESSI), the currently most capable mission in this energy range.This increase in sensitivity opens new windows for high-energyheliophysics, and will likely produce paradigm-shifting findings.The PI of this proposal was recently elected by the NuSTAR sciencesteering committee as a NuSTAR science team member in charge of planning solar observations and leading the solar science. This opportunityprovides a unique chance for our group at FHNW to establish itself throughthis high-profile project.The two major scientific problems proposed to be addressed by thesesensitive hard X-ray observations are: 1) Coronal heating by microflares,and 2) Mechanisms of electron acceleration in flares and Coronal MassEjections (CME). Besides data analysis and interpretation, the tasks wouldalso include participation in the planning of observations as well asmaking spectral and spatial simulations of the expected NuSTARobservations in preparation for the first solar observations with NuSTAR.The proposed tasks complement already existing projects at FHNW, and would greatly help to establish the newly founded group as the world-wideleading experimental and observational facility in high-energy Heliophysics.
