Abstract

PURPOSE:To obtain easily a high density and uniform electron beam by specifically designating the crystal direction of a needlelike chip axis and holding the needlelike chip on a supporter in order to facilitate cleaning the surface of the needlelike chip. CONSTITUTION:The needlelike chip 1, consisting of a carbide or nitride single crystal whisker having a sodium chloride type crystal structure, is held by the conductive support 2. The orientation of the crystal axis of the needlelike chip 1 is designaed <111>. In an electron emission cathode with such a constitution, the cleaning of the needlelike chip 1 can be performed by heating it at a high temperature under a high vacuum.
