Preprint submitted to Elsevier 4 September 2008 We have observed cosmic-ray electrons from 10 GeV to 800 GeV by a long duration balloon flight using Polar Patrol Balloon (PPB) in Antarctica. The observation was carried out for 13 days at an average altitude of 35 km in January 2004. The detector is an imaging calorimeter composed of scintillating-fiber(More)
Simultaneous measurements of high-frequency pump-enhanced airglow and ionospheric temperatures at auroral latitudes Abstract: Simultaneous measurements of enhanced airglow at 6300Å and plasma temperatures from transmitting a powerful high frequency electromagnetic pump wave from the EISCAT-Heating facility into the ionospheric F region at auroral latitudes(More)
