This paper discusses the effective limiting heavy-ion induced single-event upset cross section of radiation-hardened 150 nm SOI SRAM and the resistance of the active-delay element (ADE) used in the memory cell. The effective limiting upset cross-sect

The results of proton-induced single-event upset (SEU) measurements on radiation hard silicon-on-insulator (SOI) CMOS SRAMS are discussed and compared with a generalized figure-of-merit (FOM) prediction. Fairly large differences between the measured

Heavy ion and proton single event upsets of 4 M SOI SRAM with a hardened delay element in each memory cell were evaluated. These 4 M SRAM were fabricated in UNIBOND substrates using a radiation hardened partially depleted silicon-on-insulator CMOS te

Historically, proton-induced single-event effects (SEES) ground test data are collected independent of the orientation of the microelectronic device to the proton beam direction. In this study, we present experimental and simulation evidence that sho

Acceleration of electrons by a field-aligned electric field during a magnetospheric substorm in the deep geomagnetic tail is studied by means of a one-dimensional electromagnetic particle code. It was found that the free acceleration of the electrons

A multiyear light curve of the low mass X-ray binary, Scorpius X-1, is constructed based on the Compton Gamma Ray Observatory Burst and Transient Source Experiment (BATSE) Spectroscopy Detector (SD) data in the nominal energy range of 10-20 keV. A de

An attempt is made to reconcile two competing views as to where the auroral distribution maps from in the magnetosphere. The structure of the aurora is shown to have two distinctive parts which vary according to the magnetic activity. The low latitud

We have completed an internal calibration of 4.4 years of BATSE 10–20 keV SD data for Sco X-1. The resulting light curve shows variations on time scales from hours to weeks. A full description of the calibration used in arriving at this light curve
