Abstract
The miniature cold field emitters are very attractive for utilization in low-power gyrotrons operating in range of short millimeter and terahertz waves. But such emitters are usually nondurable when exploiting in technical vacuum. Multi-tip field emitters with protective coatings developed and investigated by the authors are promising for use in short-wave gyrotrons operating in a technical vacuum.
