    摘要： A photomultiplier tube having an ion suppression electrode positioned between a photocathode and an electron multiplying device in the photomultiplier tube is disclosed. The ion suppression electrode includes a grid that is configured to provide sufficient rigidity to avoid deformation during operation of the photomultiplier tube. The photomultiplier tube also includes a source of electric potential connected to the electron multiplying device and to the ion suppression electrode to provide a first voltage to the second electrode and a second voltage to the suppression grid electrode wherein the second voltage has a magnitude equal to or greater than the magnitude of the first voltage. A method of making the photomultiplier and a method of using it are also disclosed.

    摘要： An MCP unit of the present invention has a triode structure with a structure to achieve a desired time response characteristic independent of restrictions from a channel diameter of MCP, and is provided with an MCP group, a first electrode, a second electrode, an anode, and an acceleration electrode. Particularly, the MCP unit further comprises an electron lens structure for confining reflected electrons emitted from the anode in response to incidence of secondary electrons from the MCP group, within a space between the acceleration electrode and the anode.

    摘要： The present invention relates to a low-resistance MCP with an expanded dynamic range and excellent environment resistance, in comparison with the conventional technology. The MCP has a double structure composed of hollow first cladding glasses whose inner wall surfaces function as channel walls, and a second cladding glass having an acid resistance higher than that of the first cladding glasses.
