摘要： The MCP assembly of this embodiment is formed at least of a conductive upper support member, an MCP unit, an output electrode, a flexible sheet electrode, and a conductive lower support member as a structure for improving handleability of a flexible sheet electrode having a mesh area. The flexible sheet electrode includes the mesh area provided with plural openings. The flexible sheet electrode and the lower support member are physically and electrically connected to each other, and the flexible sheet electrode is sandwiched between the upper support member and the lower support member. As a result, even if the flexible sheet electrode becomes thin as an opening ratio of the mesh area increases, potential is set while the flexible sheet electrode is firmly held in the MCP assembly.

摘要： A phosphor screen for a Micro-Electro-Mechanical-Systems (MEMS) image intensifier includes a wafer structure, a lattice of interior walls, a thin film phosphor layer, and a reflective metal layer. The wafer structure has a naturally opaque top layer and an active area defined within the naturally opaque top layer. The lattice of interior walls is formed, within the active area, from the naturally opaque top layer. The thin film phosphor layer is disposed in the active area, between the lattice of interior walls. The reflective metal layer that is disposed atop the thin film phosphor layer. In at least some instances, the thin film phosphor layer is a non-particle phosphor layer.

摘要： A monocrystalline scintillator comprises a monocrystal and an optical plate wherein a first side of the monocrystal is adhered to the optical plate. The monocrystal comprises at least one of a rare earth garnet, a perovskite crystal, a rare-earth silicate, and a monocrystal oxysulphide. The scintillator assembly includes an adhesive adhering the optical plate to the first side of the monocrystal. The adhesive can comprise an ultra-high vacuum compatible adhesive. The adhesive is substantially transparent and has a refractive index matching the optical plate. The scintillator assembly can also include a reflective coating on the second side of the monocrystal. The monocrystalline scintillator assembly can be incorporated in a microchannel plate image intensifier tube to provide improved spatial resolution and temporal response.

摘要： Provided is a compact device which captures, over a large solid angle range, electrically charged particles emitted from a point source and parallelizes the trajectories of said charged particles. The present invention is configured from: an electrostatic lens comprising a plurality of axisymmetric electrodes (10-14) and an axisymmetric aspherical mesh (2) which has a surface that is concave away from the point source; and a flat collimator plate (3) positioned coaxially with the electrostatic lens. The acceptance angle for the electrically charged particles generated from a point source (7) is ±30° or greater. The shape of the aspherical mesh (2), and the potentials and the positions of a ground electrode (10) and application electrodes (11-15) are adjusted so that the trajectories of the electrically charged particles are substantially parallelized by the electrostatic lens. The electrostatic lens and the flat collimator plate are positioned on a common axis.

摘要： 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.
