    摘要: An electron multiplier tube including grid type of plural dynode arrays (6) arranged in a first direction with a multistage structure for successively multiplying electrons incident on them and an anode (4) provided below the multistage structure of dynode arrays (6) for collecting the multiplied electrons to output an amplified electrical signal. Each of the dynode arrays (6) includes plural rod-shaped dynode elements (9) arranged in a second direction and a mesh electrode (10) provided over each of the dynode arrays for providing an equipotential. The multistage structure of dynode arrays includes at least one group of neighbouring dynode arrays (6₄,6₅;6₆,6₇;6₈,6₉) whose dynode elements are arranged so as to be aligned with one another in the said first direction. Each of the dynode elements (9) has a substantially isosceles trapezoid section, both side legs of the trapezoid being slightly inwardly curved effectively to receive the incident electrons which have been emitted from an earlier dynode array.

    摘要: A vacuum vessel is configured by hermetically joining a faceplate (13) to one end of a side tube (15) and a stem (29) to the other end via a tubular member (31). A photocathode (14), a focusing electrode (17), dynodes (Dyl-Dy12), a drawing electrode (19), and anodes (25) are arranged within the vacuum vessel. The dynodes (Dy1-Dy12) and the anodes (25) have a plurality of channels in association with each other. The drawing electrode (19) is placed on electrically-conductive supporting pins (21) penetrating the stem (29).. The dynodes (Dy1-Dy12) are stacked with insulating members (23) interposed between one another. Since the supporting pins (21) and the insulating members (23) are arranged coaxially, each electrode can be fixed by applying pressure in z-axis direction. At the same time, emission of light between the anodes (25) and the drawing electrode (19) can be suppressed, thereby enabling noise to be reduced.

    摘要: The Venetian blind dynode (5A) and metal channel dynodes (5B) of a dynode section (5), together with insulation spacers (insulation plates) (11), are fitted on pillars (9) erected on a stem plate (3) constituting a vacuum vessel, in which state the Venetian blind dynode (5A), metal channel dynodes (5B) and insulation spaces (insulation plates) (11) are integrally firmly supported by the pillars (9); therefore, the Venetian blind dynode (5A), metal channel dynodes (5B) and insulation spaces (insulation plates) (11) have no possibility of causing accidental lateral deviation due to vibration or shock, thus ensuring that the dynode section (5) develops excellent vibration resistance performance.

    摘要: A dynode (8) constituting an electron multiplier or a photomultiplier is provided with eight rows of channels (15) each defined by an outer frame (16) and a partitioning part (17) of the dynode (8). In each channel (15), a plurality of electron multiplying holes (14) are arranged. In specified positions of the outer frame (16) and the partitioning part (17) of the dynode (8), glass receiving parts (21) wider than the outer frame (16) and the partitioning part (17) are provided integrally with the dynode (8). Glass parts (22) are bonded to all the glass receiving parts (21). The glass parts (22) are bonded by applying glass to the glass receiving parts (21) and hardening the glass and each have a generally dome-like convex shape. Each dynode (8) is formed after the dome-like glass part (22) is bonded to the glass receiving part (21).
