Abstract: The disclosure is directed to a photomultiplier tube with extended dynamic range. According to various embodiments, a repulsive electric field is introduced between a photocathode and a plurality of dynodes in order to repel or block low-energy electrons from reaching and being multiplied by the dynodes. As a result, time intervals between current peaks and drops may be decreased because the photomultiplier current will be primarily affected by high-energy electrons emitted by the photocathode in response to incident illumination versus low-energy electrons, some of which may result from dangling bonds or slow surface states after illumination no longer impinges the photocathode. Dynamic range and optical responsiveness of the photomultiplier tube are increased accordingly.

Abstract translation: 本公开涉及具有扩展动态范围的光电倍增管。 根据各种实施例，在光电阴极和多个倍增电极之间引入排斥电场，以排斥或阻止低能电子达到和乘以倍增电极。 结果，电流峰值和电压下降之间的时间间隔可能会降低，因为光电倍增管电流将主要受到光电阴极响应于入射照射与低能电子发射的高能电子的影响，其中一些可能由悬挂键 或照明后的表面状态不再影响光电阴极。 光电倍增管的动态范围和光响应性相应增加。

Abstract: 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 tubular member is disposed on the periphery of the stem, and supporting pins and lead pins penetrate and are fixed to an extending section that protrudes from the tubular member. The supporting pins and the lead pins are arranged in cutout portions of the dynodes and the drawing electrode, thereby allowing effective areas of each electrode to be enlarged. Further, protuberant sections are formed on the connecting sections of each pin with the stem, thereby facilitating thickness control of the stem.

Abstract: 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. At the center of the stem (29) an air discharging tube (40) is connected. The air discharging tube (40) includes an outer side tube (41) and an inner side tube (43), which are disposed coaxially and connected to each other at the stem (29) side. The outer side tube (41) has high adhesiveness with the stem (29) and the inner side tube (43) is thin and has small stress when being cut, thereby enabling the joint with the vacuum vessel not to be damaged when the air discharging tube (40) is sealed.

Abstract: A light detection apparatus is described. The apparatus includes a photomultiplier tube having a window for receiving light incident thereon. A photocathode is affixed to an inner surface of the window in a known manner. The apparatus further includes an optical fiber and a means for coupling the optical fiber to the window of said photomultiplier tube so that light can be introduced into the window at an angle that results in total internal reflection of the light. The coupling means may be embodied as a fiber optic terminal connector. Alternatively, the coupling means may include a prism affixed to the outside surface of the window.

Abstract: The present invention relates to a photomultiplier that realizes significant improvement of response time properties with a structure enabling mass production. In the sealed container, a photocathode, a dynode unit including at least one dynode set, and preferably dynode sets of two series, a focusing electrode unit arranged between the photocathode and the dynode unit are housed. The focusing electrode unit is set to the same potential as the second dynode arranged at a position where secondary electrons from said first dynode, which emits secondary electrons in response to incidence of photoelectrons, arrive, and is provided with partitioning plates partitioning the second dynode into two in a longitudinal direction of the second dynode.

Abstract: The present invention relates to a photomultiplier that realizes significant improvement of response time properties with a structure enabling mass production. The photomultiplier comprises a sealed container, and the sealed container includes a hollow body section, extending along a tube axis, and a faceplate. The faceplate has a light incidence surface and a light emission surface on which a photocathode is formed. In particular, the light emission surface is constituted by a flat region, and a curved-surface processed region that is positioned at a periphery of the flat region and that includes edges of the light emission surface. A surface shape of the peripheral region of the light emission surface of the faceplate is thus intentionally changed in order to adjust the angles of emission of photoelectrons from the photocathode positioned at the peripheral region. Thus, the spread of transit times of photoelectrons propagating from the photocathode to a first dynode is thus reduced effectively and made not to depend on the emission positions of the photoelectrons.

Abstract: The edges of portions of a base member that are joined to stem pins are arranged as bottom surfaces of recesses formed in the stem so that the stem pins are joined to the base member at gradual angles and so that even when a bending force acts on the stem pins, the stem pins will contact the peripheral portions at the open sides of the recesses, thereby preventing further bending of the stem pins and preventing the forming of cracks at both sides of the portions at which the stem pins are joined to the base member. Furthermore, triple junctions, at which the conductive stem pins, the insulating base member to which the stem pins are joined, and vacuum intersect, are positioned inside the recesses and put in concealed-like states.
