ABSTRACT:
A collector for an electron beam tube includes a ceramic cylinder within which are located rings of a first material, such as copper, and rings of a second material, such as molybdenum, arranged alternately along the longitudinal axis of the cylinder. The ratio of the axial lengths of the rings at the inner surface of the ceramic cylinder is selected so as to provide temperature compensation. The rings of one material surround part of adjacent rings of the other material to confine thermal expansion in a radial direction.
