Abstract
An electron beam emitter comprises a housing enclosing a cathode capable of emitting electrons within the housing and a window for allowing the emitted electrons to exit the housing, wherein the housing has an opening adapted to be at least partly engaged with a high voltage connector assembly, the assembly being adapted to connect the cathode to a power supply, the electron beam emitter further comprising a cooling flange surrounding the opening and having an interior channel extending between an inlet port and an outlet port for receiving cooling fluid for cooling the high voltage connector assembly. The invention further relates to a method of cooling an electron beam device.

An electron beam emitter comprising a housing enclosing a cathode configured to emit electrons within said housing and a window for allowing said emitted electrons to exit said housing wherein said housing has an opening adapted to be at least partly engaged with a high voltage connector assembly, said housing possessing an outer surface, said assembly being adapted to connect said cathode to a power supply, said electron beam emitter further comprising
- a cooling flange surrounding said opening and having an interior channel extending between an inlet port and an outlet port for receiving cooling fluid for cooling said high voltage connector assembly,
- wherein the cooling flange is located on the outer surface of the housing, and
- wherein the interior channel of the cooling flange is formed by interior walls of the cooling flange and the outer surface of the housing.
