Abstract: An ion feedback electron multiplier has an envelope containing an ionizable gas. Within the envelope is a chain of multiplier dynodes divided into two planar groups spaced from and parallel to one another. At one end of the multiplier chain is an electron source capable of emitting electrons upon ion bombardment. An electron lens which is between the multiplier chain and the electron source, focuses the electrons from the source onto one of the dynodes of the multiplier.

Abstract: A plurality of parallel, planar, area electron multipliers are mounted on a substrate having a plurality of electrical conductors in a coded pattern and a planar electron source thereon. Each multiplier comprises a plurality of dynode members, at least one of which is addressable, for controlling the generation of a linear electron beam which defines one video line in a flat image display device. Random or sequential generation of video lines is accomplished by generating unique combinations of electron repelling and accelerating voltages which are applied to the addressable dynode members through the coded electron conductors.

Abstract: An electrode includes an electron or irradiation transmissive conducting layer and an electron-emissive layer of insulating material in spongy form. This layer may be of BaF2, LiF2, MgF2, MgO, Al2O2, CsI, KCl or NaCl and preferably has a density of only about 1% of the same material in bulk form, e.g. 0.01 to 0.1 gms. per cc. with a thickness of 10 to 100 m . The layer may be formed by deposition in a gaseous atmosphere, e.g. argon at 1 to 2 mm. of Hg pressure, with a spacing of about 3 inches between the evaporator and the receiver, which may be rotating. Alternatively magnesium may be burnt in air at atmospheric pressure about 14 inches from the receiver. The receiver may be an aluminium film supported by a metal ring and formed by vacuum deposition of aluminium on to a film of thermally removable cellulose nitrate to a thickness of 140 to 1000 . Specifications 792,507, 862,211 and 898,433 are referred to.

Abstract: A device configured to convert or amplify a particle, the conversion or amplification being reliant on the impact of a particle on a surface of the device causing emission of one or more secondary electrons from the same surface. The device includes a carbon-based layer capable of secondary electron emission upon impact of a particle. The surface may be used to convert, for example, an ion into an electron signal, or an electron signal into an amplified electron signal, such as in conversion or amplification dynodes.

Abstract: An ion detector includes a first dynode, a second dynode, a scintillator, a conductive layer, and a photomultiplier tube. The first dynode is configured to emit a charged particle in response to the incidence of the ion. The second dynode is configured to be given a negative potential and emit a secondary electron in response to incidence of the charged particle from the first dynode. The scintillator includes an electron incident surface arranged to receive the secondary electron from the second dynode, and is configured to convert the secondary electron into light. The conductive layer is disposed on the electron incident surface. The photomultiplier tube is configured to detect the light from the scintillator.

Abstract: Ion detectors of the type used in scientific instrumentation, such as mass spectrometers. More particularly, a self-contained particle detector includes an enclosure formed in part by a transmission mode secondary electron emissive element, the enclosure defining an internal environment and an external environment, wherein the transmission mode secondary electron emissive element has an externally facing surface and an internally facing surface and is configured such that impact of a particle on the externally facing surface causes emission of one or more secondary electrons from the internally facing surface.

Abstract: An electron multiplier apparatus of the type used in ion detectors, and modifications thereto for extending the operational lifetime or otherwise improving performance. The electron multiplier includes a series of discrete electron emissive surfaces configured to provide an electron amplification chain, the electron multiplier being configured so as to inhibit or prevent a contaminant from entering into, or passing partially through, or passing completely through the electron multiplier. The electron multiplier may include one or more baffles configured. so as to decrease vacuum conductance of the electron multiplier compared to the same or similar electron multiplier not having one or more baffles.
