摘要： 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.

摘要： In an electron tube, one end of an insulating tube is protruded toward the inside of an envelope, and an avalanche photodiode (APD) is provided on the one end of the insulating tube. Another end of the insulating tube is connected to an outer stem of the envelope. Alkali sources are provided inside the envelope. The alkali sources are disposed inside the envelope and generates alkali metal vapor to thereby form a photocathode on a predetermined part of the internal surface of the envelope. The alkali sources and insulating tube are isolated from each other by a separating member. When the electron tube is manufactured, the alkali metal vapor that is generated from the alkali sources is not deposited on the insulating tube due to existence of the separating member. This prevents voltage resistance between the envelope and APD from being decreased and the electrical field in the electron tube from being adversely affected, thereby preventing incident efficiency of electrons to the APD from being decreased.

摘要： This invention relates to an electron tube having a structure for enabling a stable operation for a long time. In the electron tube, at least a confining mechanism is arranged between a photocathode and the electron incident surface of a semiconductor device, which are arranged to oppose each other. In the arrangement, the area of the opening of the confining mechanism is at least equal to or smaller than that of the electron incident surface, thereby confining the orbits of photoelectrons from the photocathode. This structure avoids bombardment of electrons arriving at portions other than the electron incident surface of the semiconductor device and prevents the semiconductor device from being unnecessarily charged.

摘要： The present invention concerns a photomultiplier having a lamination structure of fine mesh dynodes arranged at predetermined intervals, capable of detecting photons even in a high magnetic field. This photomultiplier is arranged so that hollow pipes penetrating electrodes for supporting the fine mesh dynodes define the lamination structure of an electron multiplier unit. This arrangement permits the intervals between the fine mesh dynodes to be accurately controlled, thereby obtaining the photomultiplier production errors of which are well suppressed and preventing that the fine mesh dynodes are ripped.

摘要： The present invention relates to a linear multi-anode photomultiplier or electron multiplier on which a plurality of light beams to be measured or energy beams of electrons, ions and so forth are incident one-dimensionally. The object of the present invention is to prevent crosstalk between dynode arrays caused by leaking electrons. A transmission type photomultiplier is characterized in that the direction of secondary electron emission of the first-stage dynode of each dynode array is set in the opposite direction at 180.degree. from that of an adjacent dynode array. Then, adjacent dynode arrays will not oppose each other but are shifted from each other at a predetermined distance in the lateral direction. Accordingly, even if electrons leak from a gap between dynodes of a certain dynode array, the leaking electrons will not enter the adjacent dynode array, thereby preventing crosstalk.
摘要翻译：本发明涉及一种线性多阳极光电倍增管或电子倍增器，其中待测量的多个光束或电子，离子等的能量束一维地入射。本发明的目的是防止由电子泄漏引起的多极阵列之间的串扰。透射型光电倍增管的特征在于，将每个倍增电极阵列的第一级倍增电极的二次电子发射方向设定为与相邻的倍增极阵列的方向相反的方向为180°。然后，相邻的倍增电极阵列不会彼此相对，而是在横向上以预定距离彼此偏移。因此，即使电子从某个倍增电极阵列的倍增电极之间的间隙泄漏，泄漏的电子将不会进入相邻的倍增极阵列，从而防止串扰。

摘要： The present invention relates to a photomultiplier that realizes significant improvement of response time properties with a structure enabling mass production. The photomultiplier comprises an electron multiplier section for cascade-multiplying photoelectrons emitted from said photocathode. The electron multiplier has a structure holding at least two dynode sets while sandwiching the tube axis of a sealed container in this the electron multiplier is housed. In particular, the first dynodes respectively belonging to the two dynode sets are arranged such that their back surfaces opposing respective secondary electron emitting surfaces face each other while sandwiching the tube axis. In this arrangement, because each first dynode itself is positioned near the tube axis, the efficiency of collection of photoelectrons arriving at the periphery of the first dynode is improved significantly.

摘要： 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.

摘要： Therefore, use of the electron lens forming electrodes 115 and 117 flattens the potential distribution in the longitudinal direction of the first dynode 107a in front of the first dynode 107a, that is, between the dynodes 107a and 107b. As a result, both photoelectrons emitted from the peripheral edge of the cathode 3 and photoelectrons emitted from the center region of the cathode 3 travel substantially in a straight line from the first dynode 107a after being multiplied thereby to impinge on the second dynode 107b. Since this structure reduces deviation in the transit distance of photoelectrons based on the irradiated position of light on the cathode 3, the structure also reduces the cathode transit time difference (CTTD) according to the irradiated position of light and a transit time spread (TTS) when light is irradiated on the entire surface. In particular, since the transit distance between the dynodes 107a and 107b is greater than that between other dynodes, the CTTD and TTS can be effectively reduced by providing the electron lens forming electrodes 115 and 117.
摘要翻译：因此，使用电子透镜形成电极115和117使第一倍增电极107a前面的第一倍增电极107a的长度方向上的电位分布平坦化，即在倍增电极107a和107b之间。结果，从阴极3的周缘发射的光电子和从阴极3的中心区域发射的光电子从乘法后的第一倍增电极107a基本上以直线行进，从而撞击在第二倍增电极107b上。由于该结构基于阴极3上的照射位置减少光电子的传送距离的偏差，所以结构还根据光的照射位置和通过时间扩展（TTS）减小阴极通过时间差（CTTD）当光照射在整个表面上时。特别地，由于倍增电极107a和107b之间的传输距离大于其他倍增电极之间的传输距离，所以可以通过提供电子透镜形成电极115和117来有效地减小CTTD和TTS。
