e/Noble diode pump

Information
has gloss	eng: A noble diode pump is a type of ion pump used in high vacuum applications that employs both a chemically reaction cathode, such as titanium, and an additional cathode composed of tantalum. The tantalum cathode serve as a high-inertia crystal lattice structure for the reflection and burial of neutrals, increasing pumping effectiveness of inert gas ions.
