| titleOfInvention | Electron source and X-ray tube provided with the same |
| abstract | The electron source (3) of the present invention includes a focusing electrode (33) disposed around the thermionic source (31), an equipotential line forming portion (33a) that forms an equipotential line around the thermionic source. The equipotential line forming portion is divided into a support portion (33b) that supports the equipotential line forming portion, and the equipotential line forming portion is formed using a material having a higher voltage resistance than the support portion. The support portion is formed using a material having a lower coefficient of thermal expansion. Thereby, even when the thermoelectron source is heated and the temperature of the member rises, it is possible to maintain the positional accuracy of the member and to prevent discharge. |
