Abstract : The main objective of the experiment is to examine temporal features in the auroral zone X-ray fluxes above 30 kev photon energy with resolution to intervals as short as a few milliseconds. It is primarily desired to apply high resolution analysis to small and moderate auroral X-ray fluxes which occur with much greater frequency than do extremely high fluxes. The X-ray detector is a thallium activated sodium iodide scintillation crystal five inches in diameter and one-half inch thick. The overall energy resolution due to detector effects varied from 25 to 35 per cent FWHM. (Author)
