Brief Description:
The Cosmic Ray Effects on Microelectronics (CREME) software package allows a
spacecraft designer or operator to estimate error rates arising from cosmic ray
bombardment of satellite microelectronics. Program functions include
calculation of (1) differential and integral cosmic ray flux (for any element)
vs. particle energy or vs. linear energy transfer (LET), (2) geomagnetic
shielding for a given orbit using the tabulation of geomagnetic cutoff values
by Shea and Smart (1975) as described by Adams et al. (1983), (3) ordinary and
worst-case solar flare proton fluxes, and (4) single event upset rates for
microelectronics in the orbiting satellite. More information about recent
updates and future plans can be found at the
CREME homepage.
Availability: The 1996 beta version of CREME can be accessed at the CREME homepage. The 1986 version is available on tape from the National Geophysical Data Center, E/GC2, 325 Broadway, Boulder, Colorado 80303, (303) 497-6346 ($90)
