    Abstract: A focused electron/bombarded (FEB) ion detector comprising an MCP, focusing means, and a collection anode disposed in a detector body. The collector anode includes a diode for receiving the focused output electron beam from the MCP. The gain between the input ion current to the MCP and the detector output signal from the diode is on the order of 1-100 million, depending on the device configuration and applied biasing voltages. A hybrid photomultiplier tube includes a photocathode, a photodiode for collecting and multiplying electrons emitted by the photocathode and providing an output signal and electrodes for focusing the electrons on the photodiode. A vacuum envelope encloses a vacuum region between photocathode and the detector. A conductor disposed on or adjacent to a sidewall of the vacuum envelope reduces the effect of electrical charges on the inside wall of the vacuum envelope on the trajectories of the electrons.

    Abstract: A photomultiplier assembly includes a tubular member of high magnetic permeability and a photomultiplier tube disposed within the tubular member. The photomultiplier tube has an encapsulated voltage distribution network attached thereto. A universal member extends longitudinally along at least a portion of the photomultiplier tube and provides a slip-fit between the photomultiplier tube and the tubular member so as to space the photomultiplier tube from the tubular member. The universal member has a retaining shoulder which projects radially inwardly between the photomultiplier tube and the voltage distribution network. A plurality of locking members are affixed between the universal member and the tubular member.

    Abstract: A semiconductor element is hermetically sealed to an evacuated electron tube envelope to provide a target electrode which collects electrons within the tube while the junction area and output electrode are external to the vacuum environment. This minimizes interaction of contaminating materials between electrodes such as a photocathode and the semiconductor.

    Abstract: The disclosure is directed to a photomultiplier tube with extended dynamic range. According to various embodiments, a repulsive electric field is introduced between a photocathode and a plurality of dynodes in order to repel or block low-energy electrons from reaching and being multiplied by the dynodes. As a result, time intervals between current peaks and drops may be decreased because the photomultiplier current will be primarily affected by high-energy electrons emitted by the photocathode in response to incident illumination versus low-energy electrons, some of which may result from dangling bonds or slow surface states after illumination no longer impinges the photocathode. Dynamic range and optical responsiveness of the photomultiplier tube are increased accordingly.
