The Extreme Ultraviolet Imaging Spectrometer (EIS) is currently under development
for flight on the Japanese Solar-B satellite. EIS uses a multilayer-coated off-axis
telescope mirror and a multilayer-coated toroidal grating spectrometer to produce
stigmatic spectra of solar regions isolated by a 1024 arcsec high slit. The
instrument produces monochromatic images either by rastering the solar image
across a narrow entrance slit or by using a very wide slit. Half of each optic
is coated to optimize reflectance at 19.5 nm, and the other half to optimize
reflectance at 27.0 nm, with each wavelength range imaged onto a separate CCD
detector. EIS can provide key dynamical and density diagnostic information not
easily available with the instruments being developed for SDO.
In this poster, we provide details of the instrument's expected performance,
and discuss how — along with the other instruments on Solar-B —
it can contribute to furthering the goals of the Living With a Star program.
