16 Citations | RS cathode is expected to be an impressive thermionic cathode with good emission properties and ion anti-bombarding insensitivity. |
6 Citations | Obtained results have great practical value for design of cathode-ray equipment. |
The faint but steady build-up of emission which continues from the cathode toward the cathode glow, suggests a considerable secondary electron emission from the cathode during the period of the primary wave propagation. | |
01 Dec 2005 5 Citations | The x-ray yield is strongly dependent on the deuterium diffusivity in the near the surface layer of cathode. |
11 Citations | This method is useful for applications, such as field-emission lamps and x-ray tubes, which do not require nanofabricated cathode structures. |
16 Citations | While accurate measurement of the spatial resolution response functions of an X-ray image intensifier at high spatial frequencies is a matter of some difficulty, it was felt that some indication of the likely spatial resolution of a low density X-ray cathode could be deduced from previously studies. |
We conclude that fixed anode x-ray tubes can be used in a magnetic field although its desired electron optics must be fairly “straight” and the cathode-anode axis must be well aligned with the field. | |
18 Citations | The experiments indicate that such cathodes ensures emission current densities averaged over the cathode surface of about 0.5 A/cm2 and can be used in high-voltage devices including microwave electronic instruments as well as portable X-ray sources. |
15 Citations | The superiority of this cathode increases when used in high resolution, high brightness electron guns where the electron extracting field is high at the cathode surface. |
The high brightness of the FE e-beam coupled with the array structure of the cold cathode allows a smoother control of the x-ray emission intensity. |
