Electron and proton aurora observed spectroscopically in the far ultraviolet
[1] The only way to get a global, instantaneous picture of the energetic particle input over the auroral oval is through spectral imaging. The major driver of auroral emissions in the high-latitude ionosphere is overall electron precipitation. However, for certain locations and times, such as the equatorial edge of the evening auroral oval, proton precipitation can be the major energy source an...
متن کاملCommissioning of the Superconductingecr Ion Source Venus *
VENUS (Versatile ECR ion source for NUclear Science) is a next generation superconducting ECR ion source, designed to produce high current, high charge state ions for the 88-Inch Cyclotron at the Lawrence Berkeley National Laboratory. VENUS also serves as the prototype ion source for the RIA (Rare Isotope Accelerator) front end. The magnetic confinement configuration consists of three supercond...
متن کاملVenus: the next Generation Ecr Ion Source
The construction of VENUS, an Electron Cyclotron Resonance ion source designed to operate at 28 GHz, is nearing completion. Tests with the superconducting magnet assembly produced axial magnetic field strengths of 4 T at injection and 3 T at extraction and a sextupole field of 2 T at the plasma wall. These fields are sufficient for optimum operation at 28 GHz. We expect a shift to higher charge...
متن کاملHemispheric asymmetry of the afternoon electron aurora
[1] Using ultraviolet images from two global auroral imagers, IMAGE FUV in the northern hemisphere and Polar UVI in the south, we present the first synoptic scale conjugate observations of the dayside aurora. We find that the morphology of the afternoon aurora is significantly different in the two hemispheres. Multiple spots in a ‘‘string of pearls’’ configuration are seen in the southern hemis...
متن کاملSource of the dayside cusp aurora
Monochromatic all-sky imagers at South Pole and other Antarctic stations of the Automatic Geophysical Observatory chain recorded the aurora in the region where the Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellites crossed the dayside magnetopause. In several cases the magnetic field lines threading the satellites when mapped to the atmosphere were inside th...
