    Abstract: The present invention relates to a photomultiplier having a structure for performing a high gain and achieving a higher productivity in a state keeping or improving an excellent high-speed response. In the photomultiplier, an electron-multiplying unit accommodated in a sealed container has a structure that enables an integrated assembly of a focusing electrode, an accelerating electrode, a dynode unit, and an anode. Specifically, the accelerating electrode composes a lower electrode and an upper electrode fixed each other by welding at a plurality of spots. The lower electrode is held at a pair of insulating support members in a state for the pair of insulating support members to grasp unitedly it together with the dynode unit and anode. Additionally, the upper electrode has one or more slit grooves for pinching a part of the pair of insulating support members. With this construction, the accelerating electrode constituted by the lower electrode and upper electrode is fixed at the pair of insulating support members in a state to be aligned with high accuracy by using the pair of insulating support members as a reference member.

    Abstract: The present invention relates to a photomultiplier having a structure that enables to perform high gain and satisfy higher required characteristics. In the photomultiplier, an electron-multiplying unit accommodated in a sealed container comprises a focusing electrode, an accelerating electrode, a dynode unit, and an anode. Particularly, at least the accelerating electrode and dynode unit are held unitedly in a state that at least a first-stage dynode and a second-stage included in the dynode unit are opposite directly to the accelerating electrode not through a conductive material. A conventional metal disk for supporting directly dynodes which are set to the same potential as that of the first-stage dynode is not placed between the accelerating electrode and dynode unit; thus, variations of the transit time of electrons may be drastically reduced while the electrons reach from the cathode to the second-stage dynode via the first-stage dynode.

In the photomultiplier, an electron-multiplying unit, placed in a sealed container, has a structure that enables an integrated assembly of a focusing electrode, an accelerating electrode, a dynode unit, and an anode. Specifically, by providing a structure for fixing directly the focusing electrode and accelerating electrode at a part of a pair of insulating support members for grasping directly the dynode unit and so on, together with the dynode unit and anode, each of the focusing electrode and accelerating electrode is aligned by using the pair of insulating support members as a reference. As a result, on assembly of the electron-multiplying unit, alignment work with high precision between the members, specific fixing members and fixing jigs becomes unnecessary, which enables to improve drastically the productivity of the electron-multiplying unit placed in the sealed container.
