Abstract: A secondary electron emissive layer resistant to infiltration and fouling. A barrier layer is formed by atomic layer deposition. The barrier layer may be an emissive layer and/or an interlayer. The barrier layer may form an interlayer that is a part of an electron amplifier positioned between an emissive layer and a resistive layer. The barrier layer is resistive to fluorine migration from either the emissive layer or the resistive layer.

Abstract: An electron tube includes a photoelectric surface, an avalanche photodiode, a focusing electrode part that accelerates and focuses the electrons E from the photoelectric surface toward the avalanche photodiode, and a casing including a stem provided with the avalanche photodiode. The stem is provided with a light incident hole through which the light is transmitted, and the periphery of the light incident hole is light-shielded by the stem. The focusing electrode part includes a first region provided with a light passage hole, and a second region provided with an electron passage hole that guides the electrons to the avalanche photodiode. The first region is formed on an axial line that connects the light incident hole and the photoelectric surface. The second region is formed on an axial line that connects the photoelectric surface and the avalanche photodiode.

Abstract: The invention provides devices, device configurations and methods for improved sensitivity, detection level and efficiency in mass spectrometry particularly as applied to biological molecules, including biological polymers, such as proteins and nucleic acids. In one aspect, the invention relates to charged droplet sources and their use as ion sources and as components in ion sources. In another aspect, the invention relates to charged droplet traps and their use as ion sources and as elements of ion sources. Further, the invention relates to the use of aerodynamic lenses for high efficiency ion transport to a charge particle analyzer, particularly a mass analyzer. Devices of this invention allow mass spectral analysis of a single charged droplet. The ion sources of this invention can be combined with any charge particle detector or mass analyzer, but are a particularly benefit when used in combination with a time of flight mass spectrometer.

Abstract: A photomultiplier tube comprises an evacuated envelope including a faceplate and a sidewall. A conductive coating is disposed annularly around an interior portion of the sidewall adjacent to the faceplate and on a longitudinally extending portion of the sidewall as a strip. A photoemissive cathode is disposed on an interior surface of the faceplate and on the conductive coating adjacent thereto. A shield cup is spaced from the cathode and centered within the envelope by a plurality of bulb spacers. An electron multiplier cage assembly abuts the shield cup and is attached thereto. A cathode contact assembly is in contact with the strip on the sidewall. A plurality of locating slots are formed in the base of the shield cup to orient the bulb spacers in contact with the sidewall of the envelope and spaced from the longitudinally extending strip portion of the conductive coating thereon. The bulb spacers include stop shoulders which retain the bulb spacers within the locating slots. The cathode contact assembly includes a cathode contact support member and a resilient cathode contact member. The cathode contact support member includes an electrical contact tab struck from the body thereof and a cathode support tab which includes an extruded area to circumferentially locate the resilient cathode contact member between two consecutively spaced bulb spacers and to align the resilient cathode contact member with the longitudinally extending strip portion of the conductive coating on the sidewall of the envelope.

Abstract: A photomultiplier tube comprises an evacuated envelope having a photoemissive cathode, a shield cup spaced from the cathode and an electron multiplier cage assembly abutting the shield cup. The cage assembly includes a pair of transversely spaced support plates having a plurality of support slots formed therethrough. Each of the support plates has a distal end and a proximal end, with the proximal ends being attached to the shield cup. A light shield is disposed between the distal end of the support plates. An anode and a plurality of dynodes, at least one of which has a field mesh attached thereto, are disposed between the support plates and attached thereto by end tabs. The end tabs extend from the side of the anode and the dynodes. The aforementioned shield cup includes flaps which establish a minimum transverse spacing between the proximal ends of the support plates. The light shield has a transverse dimension substantially equal to that of the flaps to establish a minimum transverse spacing between the distal end of the support plates. The flaps and the light shield thus act, in combination, to provide a uniform minimum transverse spacing between the support plates which is greater than the transverse dimension of the anode and the dynodes to prevent distortion of the field mesh. The tab ends of the dynode and the anode are bifurcated so that one portion of selected ones of the tab ends can be formed to secure the dynodes and the anode between the support plates.
