Examination of EUV CCDs and their applications for space research of solar flares

摘要

We present characterization measurements of dark current signal at different temperatures and spectral sensitivity ofcooled backside-illuminated EUV CCD matrices intended for future solar space missions, including projects ARKA andKORTES. The measurements have been conducted inside a vacuum chamber in the 125-250 Å spectral range with theuse of tungsten laser-driven plasma as a source of EUV radiation. Applications of the EUV CCDs for contemporary andfuture space investigations of solar physics taking place in solar flares is being overviewed and discussed.
