Abstract (en)

[origin: EP0471206A1] According to the X-ray image intensifier of the present invention, supporting means (40, 42) are provided for the joint portions of envelope elements which constitute a vacuum envelope, thereby increasing the assembly accuracy thereof. Accordingly, the electrostatic electron lens formed of the focusing electrodes (26, 28, 30) fixed on the supporters operates at an improved accuracy. One embodiment of the invention provides disk like metalic supporting means with a center hole sandwiched between neighbouring joint portions of the vacuum envelope (10). <IMAGE>
