Title:
PHOTOMULTIPLIER AND RADIATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2007/099956
Kind Code:
A1
Abstract:
In a vacuum vessel structured by hermetically joining a light-receiving plate
(13) to one end of a side tube (15) and a stem (29) through a tubular member (31) to
the other, a photoelectric surface (14), a focusing electrode (17), dynodes
(Dy1 to Dy12), extraction electrodes (19), and anodes (25) are provided. The
dynodes (Dy1 to Dy12) and anodes (25) have corresponding channels. The extraction
electrodes (19) are mounted on conductive support pins (21) extending through
the stem (29). The dynodes (Dy1 to Dy12) are alternated with insulating members
(23) and they make a stack. The support pins (21) and insulating member (23) are
aligned. The electrodes are secured by pressing them in the z-axis direction.
Light is prevented from being emitted between the anodes (25) and the extraction
electrodes (19), thus reducing the noise.
