Abstract
A technique is proposed which enables one to fabricate multi‐point field emission sources of bakeable structure. The technique is based on the cathodic growth of metallic needle crystal from metal crabonyl vapors and has so far been confirmed to provide emission sources of W, Mo, and Mo2C. The field emission sources prepared by this technique are highly resistive to thermal treatment and actually yield field ions possessing satisfactory intensities when used as the ion sources of a field ion mass spectrometer. It is believed that the application of these field emission sources is not restricted to mass spectrometry but can be extended to other ion and electron optical systems. The technique may thus open new areas in field emission technology.Keywords
