Title:
PHOTOCATHODE AND ELECTRON TUBE
Document Type and Number:
WIPO Patent Application WO/2002/011168
Kind Code:
A1
Abstract:
A photocathode in which the photocathode plate can be securely fixed without using any adhesive. Even under the severe condition that a high vibration resistance is required or thermal stress occurs because of great temperature variation, it can be used widely for an image intensifier, a streak tube, or a photomultiplier. The photocathode plate (16) of the photocathode (10) is sandwiched between a faceplate (11) and a support plate (19). First pins (12, 13) buried in the faceplate (11) are joined to the support plate (19). Therefore the photocathode plate (16) can be readily fixed securely to the faceplate (11) without using any adhesive. An electron tube is also disclosed.
