摘要： Exemplary metamaterial photocathodes enable detection of light from visible through long wave infrared wavelengths. Metamaterial stacks, comprising gold, silicon, and cesium-oxide, coupled to a semiconductor allow hot electrons to efficiently enter a vacuum. The hot electrons are multiplied in a multichannel plate and directly through another vacuum towards a phosphorus screen.

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.

摘要： 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.
