RAISE is a UV/EUV Imaging Spectrographs that use only two reflections to provide stigmatic imaging over multiple wavelengths and spatial fields simultaneously. RAISE uses a single off-axis parabola telescope to scan an image of the Sun across a narrow entrance slit which feeds a toroidal variable line space (TVLS) grating spectrograph, and produces stigmatic spectra on two intensified Active Pixel Sensor (APS) cameras. Spectral Images are then built up by rastering. RAISE has an extremely high speed scanning-slit imaging spectrograph designed to observe and analyze dynamics and heating of the solar chromosphere and corona on time scales as short as 100 ms, with TRACE-like spatial resolutions, and velocity sensitivity of 1-2 km/s.

RAISE Science Questions:

Active Region Loop Dynamics

– How are temperatures and velocities related?
– Dynamics of ubiquitous helical loop structures?

High Frequency Waves in the Corona

– Are there high frequency waves in the TR and chromosphere, with energy sufficient to support the observed solar wind excitation?

Mechanisms of Small Scale Energy Release

– What are the observed small scale jet-like motions: shocks or jets?
– What is the relationship between “blinkers”, “explosive events” and “UV flashes”?

This was the third flight of RAISE. The Principal Investigator is Dr. Donald Hassler/Southwest Research Institute, Boulder, Colorado.
