Abstract:
The invention describes an emitter device (10) and a method for precisely mounting a thin film electron emitter foil into a cathode cup. Therefore, small fixing bars (71) are realized to keep fine and hence weak emitter structures in position while fixing this setup onto a cathode cup. After mounting those temporary structures are removed (72) to get the final functional emitter-cathode setup.
