    Abstract: An embodiment of the invention relates to a TOF-MS capable of performing mass spectrometry of a sample at a high throughput. The TOF-MS has an acceleration part for accelerating an ion, a detector for detecting an event of arrival of the accelerated ion, and a data processing part for performing mass spectrometry of the sample, based on a time of flight of the ion. A first structure of the detector includes an MCP, a dynode, and an anode. In the first structure, the dynode is set at a potential higher than that of an output face of the MCP. The anode is disposed at an intermediate position between the MCP and the dynode or on the dynode side with respect to the intermediate position. The anode has plural apertures and is set at a potential higher than that of the dynode.

    Abstract: 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.

    Abstract: In a micro-channel plate, an electron emission film and an ion barrier film formed on a substrate are integrally formed by the same film formation step. In this structure, the electron emission film and the ion barrier film are made as continuous and firm films and the ion barrier film can be made thinner. Since the ion barrier film is formed on the back side of an organic film, the organic film is exposed during removal of the organic film. This prevents the organic film from remaining and thus suppresses degradation of performance of the ion barrier film due to the residual organic film, so as to suppress ion feedback from the micro-channel plate and achieve a sufficient improvement in life characteristics of an image intensifier.

    Abstract: A multi-component tunable resistive coating and methods of depositing the coating on the surfaces of a microchannel plate (MCP) detector. The resistive coating composed of a plurality of alternating layers of a metal oxide resistive component layer and a conductive component layer composed of at least one of a metal, a metal nitride and a metal sulfide. The coating may further include an emissive layer configured to produce a secondary electron emission in response to a particle interacting with the MCP and a neutron-absorbing layer configured to respond to a neutron interacting with the MCP.
