Linear electron source, evaporator using linear electron source, and applications of electron sources

A linear plasma electron source (100) is provided. The linear plasma electron source includes a housing (112) acting as a first electrode, the housing having side walls (312), a slit opening (114) in the housing for trespassing of a electron beam, the slit opening defining a length direction of the...

Zusammenfassung:	A linear plasma electron source (100) is provided. The linear plasma electron source includes a housing (112) acting as a first electrode, the housing having side walls (312), a slit opening (114) in the housing for trespassing of a electron beam, the slit opening defining a length direction of the source, a second electrode (110) being arranged within the housing and having a first side (413) facing the slit opening, the first side being spaced from the slit opening by a first distance, wherein the length of the electron source in the length direction is at least 5 times the first distance, and at least one gas supply (70) for providing a gas into the housing.
