CONTOURED SUPPORT GRID FOR HERMETICALLY SEALED THIN FILM APPLICATIONS |
| 摘要 |
Systems and methods for manufacturing a vacuum device, such as an electron emitter, that includes a foil exit window palced over and joined to a support grid. In one particular method, the vacuum chamber of an electron emitter has a thin foil forming an exit window at one end. The thin foil may be titanium or any suitable material and the foil will typically enlarge during a bonding process that attaches the foil to the support grid. In one manufacturing process, the support grid is provided with a surface that has contours, typically being smooth recessed surfaces, that the foil once enlarged can lie against as the vacuum pulls the foil against the grid. |

1. An exit window for an emitter comprising:
a support plate having a series of apertures for allowing passage of a beam there through; and an exit window foil bonded over the support plate, the support, plate having a planar surface and at least one surface recess which allows portions of the exit window foil to rest within the recess to reduce wrinkle formation. |
