摘要： The present invention relates to a photodetector that has a structure capable of realizing a wide range gain adjustment for each of electron multiplier channels respectively assigned to a plurality of light incidence regions of a multi-anode multiplier. The photodetector comprises a multi-anode photomultiplier, and a bleeder circuit unit. The multi-anode multiplier has a dynode unit constituted by N (an integer or no less than 3) dynode plates, and n-th (an integer of no less then 2) dynode plate is constituted by a plurality of control plates respectively corresponding to the multiplier channels. The bleeder circuit unit has a primary section setting each potential of a first to (n−1)-th and (n+1)-th to N-th dynode plates, and a secondary section for individually setting a potential of each control plate at any potential within the range wider than a potential difference between the (n−1)-th and (n+1) dynode plates. By expanding the potential setting range for the control plates rather than the potential difference between the dynode plates adjacent to the n-th dynode plate, the gain of each electron multiplier channel can be controlled by two digits or more.

摘要： A vacuum vessel is configured by hermetically joining a faceplate to one end of a side tube and a stem to the other end via a tubular member. A photocathode, a focusing electrode, dynodes, a drawing electrode, and anodes are arranged within the vacuum vessel. The dynodes and the anodes have a plurality of channels in association with each other. The drawing electrode is placed on electrically-conductive supporting pins penetrating the stem. The dynodes are stacked with insulating members interposed between one another. Since the supporting pins and the insulating members 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 and the drawing electrode can be suppressed, thereby enabling noise to be reduced.

摘要： A vacuum vessel is configured by hermetically joining a faceplate to one end of a side tube and a stem to the other end via a tubular member. A photocathode, a focusing electrode, dynodes, a drawing electrode, and anodes are arranged within the vacuum vessel. The dynodes and the anodes have a plurality of channels in association with each other. Each electrode has cutout portions that overlap in a stacking direction, and supporting pins and lead pins are arranged in the cutout portions. A bridge is provided in a concave section arranged between unit anodes, and the bridge is cut off after the anode plate is placed on stem pins. Effective areas of each electrode and the anode are secured sufficiently, thereby allowing electrons to be detected efficiently.

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 (Dy1-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.
