Energetic Particle Contamination in STIX During Solar Orbiter's Passage Through Earth's Radiation Belts and an Interplanetary Shock
Krucker, Säm; Dresing, Nina; Xiao, Hualin +8 more
The Spectrometer/Telescope for Imaging X-rays (STIX) is a hard X-ray imaging spectrometer on board the ESA and NASA heliospheric mission Solar Orbiter. STIX has been operational for three years and has observed X-ray emission from ~35,000 solar flares. Throughout its lifetime, Solar Orbiter has been frequently struck by a high flux of energetic pa…

Low-angle scattering of protons on the XMM-Newton optics and effects on the on-board CCD detectors
Evans, H.; Nieminen, P.; Daly, E. +3 more
Monte Carlo simulations are presented where protons are shown to propagate through X-ray telescope optics by grazing incidence scattering processes. If these protons reach charge coupled device (CCD) detectors in sufficient numbers, they can induce a radiation background, and at certain energies, the nonionising dose can cause degradation of the c…
The in-orbit performance of the Exosat gas scintillation proportional counter
Manzo, G.; Taylor, B. G.; Peacock, A. +2 more
The European X-ray observatory satellite Exosat, launched in May 1983, carries a scientific payload of four instruments designed to study the properties of cosmic X-ray sources. The present investigation is concerned with one of these instruments, taking into account the gas scintillation proportional counter (GSPC) spectrometer. Attention is give…
A space-borne plasma analyser for three-dimensional measurements of the velocity distribution
Coates, A. J.; Winningham, J. D.; Johnstone, A. D. +3 more
A new type of plasma analyzer, capable of covering the three-dimensional energy distribution of charged particles from a spinning spacecraft, has been built for the AMPTE and GIOTTO spacecraft. The novel features are the use of 260 deg of deflection in a spherical plate electrostatic analyzer to obtain energy discrimination simultaneously with dis…
