摘要

The NASA Solar Dynamics Observatory (SDO), scheduled for launch in 2009, incorporates a suite of instruments including the EUV Variability Experiment (EVE). The Multiple EUV Grating Spectrograph (MEGS) channels use concave reflection gratings to image solar spectra onto CCDs that are operated at -100℃. MEGS provides 0.1 nm spectral resolution between 5-105nm every 10 seconds with an absolute accuracy of better than 25% over the SDO 5-year mission. Characterizations and selection testing of the CCDs and the thin foil filters for SDO EVE have been performed with both in-band and visible illumination. CCD selection was based on results from testing in LASP facility Calibration and Test Equipment (CTE3) as well as results from at testingMIT. All CCDs meet the requirements for electronics gain, flat field, Quantum Efficiency (QE), dark current, reverse clock, CTE, bad pixels and the -120℃ survival test. The thin foil filters selection was based on tests performed at LASP facilities and NIST. All filters provide > 10~6 attenuation of visible light with the proper EUV transmission needed for order sorting capabilities and are free of critical pinholes.
