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

Abstract

The purpose of this research program is the evaluation and characterization of high brightness field electron and ion sources suitable for use in high density information storage systems. In addition, preliminary evaluation of focussing optics suitable for forming submicron beams of both ions and electrons has been performed. Several new field electron source materials including Mo, LaB6, SmB6 and HfC have been examined. In addition, a complete characterization and comparison between the Zr/W(100) and built-up W(100) emitters operating in the thermal-field (TF) mode is reported. Such source parameters as angular intensity, energy distribution, beam noise spectrum, and source life have been measured.
