title = "Imaging earth{\textquoteright}s magnetosphere: Measuring energy, mass, and direction of energetic neutral atoms with the isena instrument",
abstract = "ISENA (Imaging Spectrometer for Energetic Neutral Atoms) was launched on board the Argentinean-US Satellite SAC-B on 4 November 1996. The 3-axis stabilized SAC-B was to orbit the Earth at 550 km with an inclination of 38°, making it a suitable platform for detecting ENAs produced by charge exchange within Earth{\textquoteright}s magnetosphere. A failure of the spacecraft to separate from the Pegasus booster has resulted in the spacecraft{\textquoteright}s assuming an attitude which does not provide sufficient illumination of the solar panels, greatly reducing the likelihood of useful data production. ISENA's sensors are based upon the GEOTAIL/HEP-LD and CLUSTER/RAPID instruments. The instrument is comprised of two identical sensors, each with a field of view of 60° x 12°. The sensors are oriented at 90° to each other, but have parallel optic axes. Each sensor contains an entrance collimator electrically biased to reject charged particles, an entrance foil to suppress H Ly a photons and provide electrons for a start signal, two microchannel plate assemblies associated with a time-of-flight measuring system, a 4-segment anode to measure ENA arrival directions with 15° angular resolution, and a solid state detector to measure the energies of 35 keV - 150 keV ENAs. ISENA has a mass of kg and consumes 6W. The design and operating characteristics of ISENA{\textquoteright}s sensors and associated electronics are described. Simulation of the predicted ENA signal is discussed.",
