“…On the other hand, some components have been reported to have cross-sections which do not saturate in this range [5]. The impact of this increase on a total system error rate can be significant in environments for which the particle fluxes above several hundreds of MeV are not negligible as it is the case for avionic/stratospheric altitudes or a particle accelerator such as the LHC.…”

Proton experimental data are analyzed for a 16-Mbit Thin-Film-Transistor (TFT) PMOS Static Random Access Memory (SRAM) with DRAM capacitors. The presence of high-Z materials as tungsten causes an unusual increase of the Single Event Upset (SEU) proton cross-section for the energies above 100MeV. Monte-Carlo simulations reproduce the experimentally measured cross-sections up to 480MeV and predict a further increase up to GeV energies. The implications of this increase are analyzed in the context of the LHC and other radiation environments where a significant fraction of the fluence lies above 100MeV.

“…This value was in fact predicted in [10] through a fit of the Monte Carlo SEL model to the experimental data in the 100-230 MeV range. The impact of the energy dependency derived from the high-Z elements on the mixed-field cross sections (initially introduced in [12]) will be quantified in the following subsection.…”

“…This approach ignores the potential effect of the differences in the particle energy spectra of the test and operational environments. However, as shown in [12], [13] the SEL, SEU and MBU cross section energy dependence can be significantly impacted by the presence of tungsten near the relevant sensitive volumes, notably for components with high critical charges. Quantifying the risk related to the impact of the spectral hardness in atmospheric and high energy accelerator applications is the main objective of the work we present here.…”

This paper explores the relationship between monoenergetic and mixed-field Single Event Latchup (SEL) cross sections, concluding that for components with a very strong energy dependence and highly-energetic environments, test results from monoenergetic or soft mixed-field spectra can significantly underestimate the operational failure rate. We introduce a semi-empirical approach that can be used to evaluate the SEL rate for such environments based on monoenergetic measurements and information or assumptions on the respective sensitive volume and materials surrounding it. We show that the presence of high-Z materials such as tungsten is particularly important in determining the hadron cross section energy dependence for components with relatively large LET thresholds.

“…For practical applications to astronauts, communications, and satellite operations, it is recognized that the 50-MeV range is of greatest importance (Schwank et al, 2005, Posner, 2007, Tribble, 2010, although for specific applications such as single event upsets, lower (E > 30-MeV) energies are expected to be important (O'Brien, 2009). One forecast system, UMASEP, which matches derivatives of soft X-ray flare increases (N uñez, 2011) or microwave fluxes (Zucca et al, 2017) with initial increases of SEP intensities, has been extended to the 100-MeV range (N uñez, 2015).…”

-Forecasting solar energetic (E > 10-MeV) particle (SEP) events is an important element of space weather. While several models have been developed for use in forecasting such events, satellite operations are particularly vulnerable to higher-energy (>50-MeV) SEP events. Here we validate one model, the proton prediction system (PPS), which extends to that energy range. We first develop a data base of E > 50-MeV proton events >1.0 proton flux units (pfu) events observed on the GOES satellite over the period 1986-2016. We modify the PPS to forecast proton events at the reduced level of 1 pfu and run PPS for four different solar input parameters: (1) all ≥M5 solar X-ray flares; (2) all >200 sfu 8800-MHz bursts with associated ≥M5 flares; (3) all >500 sfu 8800-MHz bursts; and (4) all >5000 sfu 8800-MHz bursts. The validation contingency tables and skill scores are calculated for all groups and used as a guide to use of the PPS. We plot the false alarms and missed events as functions of solar source longitude, and argue that the longitude-dependence employed by PPS does not match modern observations. Use of the radio fluxes as the PPS driver tends to result in too many false alarms at the 500 sfu threshold, and misses more events than the soft X-ray predictor at the 5000 sfu threshold.
