The Atree Code and Database System for Analysis of Radiation Effects on Electronics
Abstract
A radiation response database and database program, called ATREE, for analyzing transient radiation effects on electronics has been developed. Neutron fluence, total dose and gamma dose rate effects can be determined by the system. The system is capable of storing and analyzing data pertaining both to individual electronic components and entire systems. Representative data for 23 types of components have been included. Utility programs are included in the ATREE system to facilitate the preparation and processing of ATR5 analyses as required to generate the radiation environment data corresponding to the user-specified source type and problem geometry. The system is user friendly and was designed so as to be easily updated or expanded. The radiation effects data base described below is intended to illustrate changes in basic performance characteristics of a variety of semiconductor devices when exposed to the various battlefield radiation environments. These environments are total ionizing dose, transient dose rate, and neutron fluence. The electrical parameters selected to demonstrate the effects of radiation are the key factors for each device type which are fundamental to design integrity in typical circuit applications. These are intended to be illustrative rather than comprehensive. The range of device types shown represent the majority of those in common usage and provide a basis for generalizing characteristics across families of parts fabricated with similar process technologies. A database program has been designed to interrogate this database, to display the results of radiation analyses using the data and to allow expansion of the database. Other related programs have been designed to allow the definition and analysis of electronic systems containing any number of parts, and to allow the execution and processing of ATRS analyses in order to create a database of radiation environments.
