Field Electron and Ion Source Research for High Density Information Storage System.

Abstract

The purpose of this research program is the development of high brightness field emission and field ion sources. A new method of preparing W/Zr TF cathodes is discussed and life test results of LaB6 field emitters are described. Built up emitters of tantalum and iridium have been examined. Results of experiment and calculation are presented for the energy distribution of field emitted electrons from substrates of varying temperature and work function. Field ionization data for several gases has been obtained. Also, noise measurements have been performed for a field ion source. (Author)
