Abstract. When flux enhancements of energetic electrons are produced as a consequence of geomagnetic storm occurrence, they tend to vanish gradually when the magnetic activity calms down and the fluxes decay to quiet-time levels. We use SAC-C and DEMETER low altitude observations to estimate the energetic electron lifetimes (E=0.16-1.4 MeV, L=1.6-5, B=0.22-0.46 G) and compare the decay rates to those observed at high altitude. While crossing the radiation belts at high latitude, the SAC-C and DEMETER instruments sample particles with small equatorial pitch angles (α eq < 18 • for L > 2.5) whereas the comparison is done with other satellite data measured mainly in the equatorial plane (for α eq > 75 • ). While in the inner belt and in the slot region no significant lifetime differences are observed from the data sets with different α eq , in the outer belt, for the least energetic electrons (<500 keV), the lifetimes are up to ∼3 times larger for the electrons with the equatorial pitch-angle close to the loss cone than for those mirroring near the equator. The difference decreases with increasing energy and vanishes for energies of about 1 MeV.

“…Particularly, we have compared in this section the SAC-C mission in-flight SER data [19] with our calculation results for the HM628512 and the KM684000 devices. The ground test data for heavy ion cross section, provided in [20], were used to extract d K and C  parameters by the ordinary least squares method (see Fig. 6).…”

-A simple physical model for calculation of the ioninduced soft error rate in space environment has been proposed, based on the phenomenological cross section notion. Proposed numerical procedure is adapted to the multiple cell upset characterization in highly scaled memories. Nonlocality of the ion impact has been revealed as the key concept determining the difference between physical processes in low scaled and highly scaled memories. The model has been validated by comparison between the simulation results and the literature on-board data. It was shown that proposed method provides single-valued prediction results correlating well with on-board data based solely on cross section data and LET spectra without any hidden fitting parameters and procedures.

Commercial off-the-shelf (COTS) technologies are increasingly used to realize compact, low-cost and high-performance on-board equipment. Before a COTS technology can be adopted in orbit, its performance must be verified in the orbit environment, where factors such as radiation must be considered. This paper presents the irradiation test results of SD cards exposed to gamma ray and proton irradiation. During the testing, we find breakdown phenomena specific to proton irradiation whereas extreme gamma ray irradiation exerts no significant effect. Moreover, the proton phenomena occurs even when the target is switched off throughout the irradiation. The anomalies induced by the irradiation are irreversible.
