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： 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： A glass container has a faceplate, a side tube, and a bottom. A photocathode is formed on the inner side of the faceplate. The glass container includes a partitioning wall, a shield electrode, a first dynode, a second dynode, a dynode array, and an anode. The partitioning wall has a cross shape to divide an electron focusing space into four space segments. The shield electrode is provided to shield the second dynode from the photocathode. A Venetian blind type of dynodes is provided as the dynode array. The first dynode, the second dynode, the dynode array, and the anode are maintained at the potential which is higher than that of the photocathode. Electrons emitted from the photocathode in response to incident light thereon efficiently impinge on the dynodes regardless of where the electrons are emitted. The electrons are multiplied and then detected by the anode.

摘要： A photomultiplier tube has a side tube with a stem plate fixed on one end and a faceplate fixed on the other. The side tube is formed of metal, and at least the portion of the stem plate contacting the metal side tube is formed of metal. The side tube and stem plate are fused together by laser welding or electron beam welding to form an airtight vessel, such that the outer edge of the stem plate does not protrude further externally than the outer surface of the side tube.

摘要： An x-ray tube 100 mainly includes an electron gun assembly 110 and a target assembly 210 which are arranged at right angles. In the target assembly 210, an x-ray target 211 is enclosed in a cylindrically-shaped hood electrode 212. Electrons emitted from the electron gun assembly 110 enters the hood electrode through an electron beam opening 215 to collide with the x-ray target 212, whereupon x-rays are generated. X-rays travel in an x-ray emitting direction R along the central axis of the hood electrode to emit outside of the hood electrode through an x-ray opening 216. A protrusion 212a is formed on the periphery of the hood electrode 212 downstream of the electron opening 215 in the x-ray emitting direction R.

摘要： Control information from a plurality of applications 1000 is written into a shared memory 101 as needed. A communication part 105 transmits the control information written in the shared memory 101 to a DHM 200 in each transmission cycle which is constant. In a management table, a plurality of allowable delay times is defined, the allowable delay time being a delay time allowable at an urgent transmission of the control information. A transmission timing notification part 106 divides a transmission cycle into time slots each of which is equal to or shorter than the shortest allowable delay time defined in the management table. The communication part 105 transmits the control information in the shared memory 101 to the DHM 200 before arrival of the transmission cycle, in a unit of time slot.
