Abstract
The present invention refers to a method for assembling an electron exit window of an electron beam generating device, comprising the steps of: arranging a foil support plate on a housing of the electron beam generating device, bonding a window foil to a frame along at least one continuous bonding line, thus creating an exit window sub-assembly, and attaching the exit window sub-assembly onto the housing. The invention also relates to an electron exit window assembly.
Claims10
An electron exit window assembly of an electron beam generating device comprising a foil support plate and a window foil, wherein
- said foil support plate is arranged on a housing of the electron beam generating device,
- said window foil is bonded to a frame along at least one continuous bonding line, forming an exit window sub-assembly, the at least one continuous bonding line being one of a laser weld, an electron beam weld, a braze, an ultrasonic weld, a diffusion bond or glue, and
- said exit window sub-assembly is brought into contact with and attached to the housing after said window foil is bonded to the frame along the at least one continuous bonding line.
An electron exit window assembly of an electron beam generating device comprising a foil support plate and a window foil, wherein
- the window foil has a top surface and a bottom surface,
- the foil support plate is arranged on a housing of the electron beam generating device,
- a portion of the bottom surface of the window foil is bonded to a frame along at least one continuous bonding line, forming an exit window sub-assembly, and the entire top surface of the window foil is exposed, the at least one continuous bonding line being one of a laser weld, an electron beam weld, a braze, an ultrasonic weld, a diffusion bond or glue, and
- the exit window sub-assembly is attached to the housing.
An electron exit window assembly of an electron beam generating device comprising a foil support plate, a frame, and a window foil, wherein
- the foil support plate is arranged on a housing of the electron beam generating device,
- the frame possesses a top surface and a bottom surface;
- the window foil is bonded to the top surface of the frame along at least one continuous bonding line, forming an exit window sub-assembly, the at least one continuous bonding line being one of a laser weld, an electron beam weld, a braze, an ultrasonic weld, a diffusion bond or glue, and
- the bottom surface of the frame contacts the foil support plate when the exit window sub-assembly is attached to the housing.
