The IMpulsive Phase Rapid Energetic Solar Spectrometer (IMPRESS): A Time Focused X-ray CubeSat
Abstract
The IMpulsive Phase Rapid Energetic Solar Spectrometer (IMPRESS) is an NSF-funded 3U CubeSat in development via a collaboration between the University of Minnesota, Montana State University, the University of California, Santa Cruz, and the Southwest Research Institute. The mission's primary goal is to measure subsecond spikes in solar flare hard X-ray flux. These spikes can help study particle acceleration in flares by correlating the properties of these spikes with the properties of particle acceleration mechanisms. The mission will also carry secondary goals: perform stereoscopic X-ray directivity measurements in conjunction with the STIX instrument onboard Solar Orbiter and to demonstrate a new, high dynamic range X-ray detector that is optimized for high count rates and fast time resolution. The detector will feature 4 CeBr3 crystals with SiPM readout and an Amptek X123 X-ray detector. IMPRESS will produce high cadence spectra in the 4-100 keV range, allowing it to constrain both thermal and nonthermal properties of solar flares.
