“…These analyses used the Sector Shielding Analysis Tool (SSAT) (Santina et al 2003) based on geant4. The simulated instrument geometry incorporated key HOPE components including all exterior walls, the interface plate between the TOF subsystem and the HEU, and the ESA subsystem.…”

The HOPE mass spectrometer of the Radiation Belt Storm Probes (RBSP) mission (renamed the Van Allen Probes) is designed to measure the in situ plasma ion and electron fluxes over 4π sr at each RBSP spacecraft within the terrestrial radiation belts. The scientific goal is to understand the underlying physical processes that govern the radiation belt structure and dynamics. Spectral measurements for both ions and electrons are acquired over 1 eV to 50 keV in 36 log-spaced steps at an energy resolution E FWHM /E ≈ 15 %. The dominant ion species (H + , He + , and O + ) of the magnetosphere are identified using foil-based time-of-flight (TOF) mass spectrometry with channel electron multiplier (CEM) detectors. Angular measurements are derived using five polar pixels coplanar with the spacecraft spin axis, and up to 16 azimuthal bins are acquired for each polar pixel over time as the spacecraft spins. Ion and electron measurements are acquired on alternate spacecraft spins. HOPE incorporates several new methods to minimize and monitor the background induced by penetrating particles in the harsh environment of the radiation belts. The absolute efficiencies of detection are continuously monitored, enabling precise, quantitative measurements of electron and ion fluxes and ion species abundances throughout the mission. We describe the engineering approaches for plasma measurements in the radiation belts and present summaries of HOPE measurement strategy and performance.

“…The difference is in the levels and particle energies encountered. The tools applied are in the first instance the standard tools at ESA also used in earth orbit like SHIELDOSE2 [9], EQFLUX [10], NIEL [11], CREME96 [12], SSAT [13], DICTAT [14], MULASSIS [15], GRAS [16]. Some of these are restricted in their capabilities for instance in the energy range, which can be treated.…”

“…This was partially corrected for by counting only daily increases in dose, and thus increases in dose smaller than the fading effect are neglected. The RADFETs were modelled using the Sector Shielding Analysis Tool (SSAT) [11] using the AE-8 MIN spectrum expected for the entire orbit and model predictions are shown. The data show that the RADFETs are detecting the same enhancements in the radiation belt as the CEDEX dose rate diodes and Merlin SURF plates, and that these are the dominant source of TID.…”

The Giove-A spacecraft carries two radiation monitors, CEDEX, built by the University of Surrey and Merlin, built by QinetiQ, to study the radiation environment encountered in the Galileo orbit. The two monitors have been functioning since the beginning of the mission and have measured protons, heavy ions and electrons. The electron environment has been found to be highly variable and driven by solar interactions. Comparisons with AE-8 indicate that the electron energy spectrum for the period measured was somewhat harder than that expected from the model. A series of large Solar proton events were detected in December 2006, registering as enhanced fluxes of protons, heavy ions and also triggering a large enhancement in the outer electron belt. Comparisons with POLE and INTEGRAL/IREM show an improved spectral match over AE-8
