Abstract
The goal of the detector development program for the Solar and Heliospheric Spacecraft (SOHO) EUV Imaging Telescope (EIT) is an Extreme UltraViolet (EUV) CCD (Charge Coupled Device) camera. The Naval Research Lab (NRL) SOHO COD Group has developed a design for the EIT camera and is screening CCDs for flight application. Tektronix Inc. have fabricated 1024x1024 CCDs for the EIT program. As a part of the CCD screening effort the quantum efficiency (QE) of a prototype CCD has been measured in the NRL EUV laboratory over the wavelength range of 256 to 735 Angstroms. A simplified model has been applied to these QE measurements to illustrate the relevant physical processes that determine the performance of the detector. 2. INTRODUCTION: THE EIT MISSION SOHO is a joint European Space Agency (ESA) and NASA project within the Solar Terrestrial Science Scientific Program. The overall objective of SOHO is the study of the solar interior and atmosphere. The solar atmosphere is defined in this context to extend from the solar photosphere out through the solar wind. The orbital station of the SOHO spacecraft is the inner Lagrangian point (''0. 99AU). This location allows the acquisition of j situ measurements of the solar wind to compare to the remote measurements of the inner solar atmosphere and solar wind.
