- Abstract
- Field emission micro-focus x-ray source based on carbon nanotube (CNT) has attractive features for biomedical or clinical imaging [1]. X-ray sources for micro-focus and/or miniature tube types require a mini-sized, high-density emission current in the order of 102~103 mA/cm 2. We have previously reported that the optimized paste composition with a nano-scale metal filler enhanced adhesion between CNT emitter and cathode electrode at low temperature [2]. In this study, a CNT-on-Tip cathode, having CNT emitter on a tungsten (W) wire of 100 μm in diameter, was developed in order to increase emission current density. © 2010 IEEE.
