Abstract: We present a definition of discrete channel surfaces in Lie sphere geometry, which reflects several properties for smooth channel surfaces. Various sets of data, defined at vertices, on edges or on faces, are associated with… read more here.

Abstract: Vacuum channel GaAs photocathode assemblies exhibit a high emission current and good structural stability, meeting the requirements for cathode emission beams in some terahertz vacuum devices. Advances are required in the design of electron sources… read more here.
