Abstract

We present results of a program to enhance the ultraviolet and extreme ultraviolet response of charge-coupled devices (CCDs). The ultimate goal of our program is to develop a large format device with both high and stable quantum efficiency from 100-3000 Å which can be used as a windowless imaging detector in a space environment. Of particular concern in this environment and at these wavelengths is long-term photometric stability under hard vacuum. We will discuss quantum efficiency and vacuum stability measurements for a number of ion implanted and laser annealed test CCDs specially fabricated by Tektronix for this program.
