Characteristics of a new type cold cathode which consists of porous MgO and Ag layers are described. After appropriate heat treatment, δ and SSE of this cathode become 103 and 6mA/cm2 respectively. The reason of obtaining such high gain may be explained by the establishment of parallel electric field in the pores of MgO layer due to the local deposition of Ag on the surface of MgO grains.
