CREME96 - A REVISION OF THE COSMIC-RAY EFFECTS ON MICROELECTRONICS CODE

CREME96 is an update of the Cosmic Ray Effects on Micro-Electronics co de, a widely-used suite of programs for creating numerical models of t he ionizing-radiation environment in near-Earth orbits and for evaluat ing radiation effects in spacecraft. CREME96, which is now available o ver the World-Wide Web (WWW) at http://crsp3.nrl.navy.mil/creme96/, ha s many significant features, including (1) improved models of the gala ctic cosmic ray, anomalous cosmic ray, and solar energetic particle (' 'flare'') components of the near-Earth environment; (2) improved geoma gnetic transmission calculations; (3) improved nuclear transport routi nes; (4) improved single-event upset (SEU) calculation techniques, for both proton-induced and direct-ionization-induced SEUs; and (5) an ea sy-to-use graphical interface, with extensive on-line tutorial informa tion. In this paper we document some of these improvements.
