摘要： The present invention relates to a photomultiplier that realizes a significant improvement of response time characteristics by a structure enabling mass production. The photomultiplier comprises a sealed container, and, in the sealed container, a photocathode, an electron multiplier section, and an anode are respectively disposed. The electron multiplier section includes multiple stages of dynode units, and each of the multiple stages of dynode units is fixed with one end of the associated dynode pin while being electrically connected thereto. In particular, the dynode pin, whose one ends are fixed to the multiple stages of dynode units, are held within an effective region of the electron multiplier section contributing to secondary electron multiplication, when the electron multiplier section is viewed from the photocathode side. By this configuration, a focusing distance from the photocathode to a first stage dynode unit can be shortened effectively and the effective region of the electron multiplier section can be enlarged to effectively reduce variations in transit time of photoelectrons propagating from the photocathode to the first stage dynode unit.
摘要翻译：本发明涉及光电倍增器，其通过能够批量生产的结构实现响应时间特性的显着改善。光电倍增管包括密封容器，并且在密封容器中分别设置有光电阴极，电子倍增器部分和阳极。电子倍增器部分包括多级倍增电极单元，并且多级倍增电极单元中的每一级在相关联的倍增极引脚的一端被电连接的同时被固定。特别地，当从光电阴极侧观察电子倍增器部分时，其一端固定到倍增电极单元的多级的倍增极销被保持在有助于二次电子倍增的电子倍增器部分的有效区域内。通过这种结构，可以有效地缩短从光电阴极到第一级倍增电极单元的聚焦距离，并且可以扩大电子倍增器部分的有效区域，从而有效地减少从光电阴极传播到第一级倍增电极的光电子的通过时间的变化单元。

摘要： The present invention relates to a photomultiplier having a fine configuration capable of realizing stable detection accuracy. The photomultiplier has a housing whose inside is maintained vacuum, and a photocathode, an electron-multiplier section, and an anode are disposed in the housing. In particular, one or more control electrodes disposed in an internal space of the housing which surrounds the electron-multiplier section and the anode are electrically connected via one or more connection parts extending from an electron emission terminal of the electron-multiplier section. In this configuration, due to a voltage, instead of the applying between an electron entrance terminal and the electron emission terminal of the electron-multiplier section, being applied between the electron entrance terminal and the control electrodes, an electric potential gradient which is increased gradually from the photocathode side toward the anode side is formed in the electron-multiplier section, and a sufficient electric potential difference is provided between the electron emission terminal of the electron-multiplier section and the anode, which makes it possible to obtain stable detection accuracy.
