Paper Abstract

Application of very fast CCD detectors to both fine pointing and tracking and to low data rate reception for free space optical communications has been demonstrated in several prior programs. CCD detector based wide field multi-channel receivers have been considered for several new applications. We are conducting a program whose goal is evaluation of radiation induced degradation in the properties of CCD devices for use in such systems. In this paper we present initial results of this ongoing effort. We present a brief overview of systems design and detector design for multi-channel low rate data receivers. Following this we present results from a comprehensive experimental determination of CCD performance degradation due to ionizing radiation. Ionizing radiation testing was accomplished using a Co60 source at the Salk Institute. Dose levels up to 1 Mrad were utilized in this test activity. We will also briefly discuss aspects of displacement damage testing activity at the University of Rochester Tandem VandeGraaff accelerator. Primary emphasis of this effort will be on evaluation of charge transfer efficiency changes due to displacement damage. Special attention is given to charge trapping phenomena and their impact on CTE. A review of test results for the ionizing radiation test portion of our program is given.
