Title:
PHOTOMULTIPLIER AND RADIATION DETECTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/111103
Kind Code:
A1
Abstract:
A photomultiplier is provided. A vacuum container (18) is constituted by airtightly bonding a light receiving surface plate (13) on one side end of a side tube (15), and a stem (50) on the other side end through a ring-like side tube (37). In the vacuum container, a focusing electrode (17), dynodes (Dy1-Dy9), an anode (25) and a dynode (Dy10) are arranged, from the side of a photoelectric surface (14) arranged on the light receiving surface plate (13). The dynode (Dy10) is supported on a spacer (33) and a positioning protrusion (31), which are arranged on the stem (50). The anode (25) is placed on the supporting member (21). The focusing electrode (17), the dynodes (Dy1-Dy9), and the anode (25) are laminated through interlayer bodies (23) coaxially arranged with the supporting member (21), and high shake proof characteristic is provided. Since there is no insulating material between the anode (25) and the dynode (Dy10), light emission is suppressed and noise is reduced.
