The Rapid Acquisition Imaging Spectrograph (RAISE) is a next-generation high resolution imaging spectrograph to study the dynamics of the solar chromosphere and corona on time scales as short as 100 ms. High speed imaging from TRACE has shown that rapid motions and reconnection are central to the physics of the transition region and corona, but cannot resolve the differences between propagating phenomena and bulk motion. SoHO/CDS and SoHO/SUMER have yielded intriguing measurements of motion and heating in the solar atmosphere, and Solar-B/EIS will capture EUV spectra of flares in progress; but no currently planned instrument can capture spectral information in the chromosphere, transition region, or cool corona on the 1-10 Hz time scale required for few-second cadence spectral imaging or rapid wave motion studies. RAISE is uniquely suited to exploring this hard-to-reach domain.The first flight of RAISE is scheduled for October 24, 2006 (Flight 36.219 US) and will focus on the study of high frequency, small-scale dynamics of active region structures and the high frequency wave structure associated with these active regions.
