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： 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。

摘要： A photomultiplier tube includes: a cathode, a plurality of dynodes, and an electron lens forming electrode. The cathode emits electrons in response to incident light. The plurality of dynodes multiplies electrons emitted from the cathode. The electron lens forming the electrode is disposed in a prescribed position in relation to an edge of a first dynode positioned in a first stage from the cathode and an edge of a second dynode positioned in a second stage from the cathode, and smoothes an equipotential surface in a space between the first dynode and the second dynode along a longitudinal direction of the first dynode. This structure improves time resolution in response to incident light.
