Energetic processes on the Sun, including particle acceleration and plasma heating during flares and quiescence, emit signatures across the electromagnetic spectrum, from X-rays/gamma-rays, through UV/EUV, to infrared and radio. Recent measurements from numerous solar observatories including RHESSI; SDO; MinXSS; SphinX; the FOXSI, Hi-C, EUNIS, and EVE rockets; the GRIPS balloon; EOVSA; and many others; and from opportunistic observations by non-solar observatories such as NuSTAR, Fermi, ALMA, and VLA, have significantly advanced our understanding of these phenomena. They have also shown the pressing need for increasingly advanced high-resolution, high-sensitivity measurements across the entire spectrum, including polarimetry and especially imaging spectroscopy, to gain further insight into these high-energy processes.

This session invites presentations covering new instrumentation, enabling technology, missions, and concepts for next-generation solar remote sensing -- including spectroscopy, imaging, and beyond -- aimed at studying high-energy (hot and non-thermal) aspects of the Sun, and the science enabled by such new observations.
