Abstract
A simple instrument to determine field emission tip work functions and shap e functions from simultaneous current-voltage (I-V) characteristics and fie ld emission energy distributions of field emitter tips and tip arrays is de scribed. This instrument uses a cylindrical energy analyzer with a few corr ecting elements to simulate a hemispherical analyzer and provides a low cos t and more compact alternative to a commercial hemispherical spectrometer. I-V curves and energy distributions may be automatically obtained as a func tion of time to study field emission tip degradation with usage and/or expo sure to gases of interest.
