Innovative Technologies taking a part in NASA EUNIS project

The Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS) sending rocket instruments a two channel imaging spectrograph that observes the solar corona with high spectral resolution and a rapid cadence made possible by unprecedented sensitivity. The rapid cadence of EUNIS is the key to its power to explore the timing variable and spatially inhomogeneous heating mechanisms that define the frontier of coronal energy. EUNIS designed to probe the structure and dynamics of the solar transition region and corona with one second time resolution. EUNIS will measure temperature, density, velocity, and elemental abundances in transient structures driven by reconnection or wave heating. Our work included a two channel EUV sounding rocket spectrograph, with over 100 times the sensitivity of the highly successful SERTS payloads, that preceded it. Our work included the flight demonstration of the cooled Active Pixel Sensor array detectors and demonstration of an advanced Toroidal Varied LineSpace grating.  This work for NASA, although challenging proved to be very rewarding and beneficial to the EUNIS Project
