An Operational Model for Microchannel Plate Devices

IEEE Transactions on Nuclear Science, 1981

The behavior of optical detectors using microchannel plates (MCPs) as electron multipliers is described in terms of the physical parameters of the MCP (channel resistance, channel capacitance, channel wall secondary emission ratio, etc.). Three operating modes are included: (1) DC operation at low light levels, (2) pulse detection operation at high peak currents, and (3) single electron counting with cascaded ...


The Behavior of "Magnetic" Electron Multipliers as a Function of Frequency

Proceedings of the IRE, 1947

This paper consists of a theoretical and experimental study of the frequency variation of gain of magnetic electron multipliers. It is shown that, for multipliers of the type studied, the behavior as a function of over-all electron transit angle is very similar to that observed for electrostatic electron multipliers previously described. Up to frequencies of about 500 megacycles, loss in ...

  • An Operational Model for Microchannel Plate Devices

    The behavior of optical detectors using microchannel plates (MCPs) as electron multipliers is described in terms of the physical parameters of the MCP (channel resistance, channel capacitance, channel wall secondary emission ratio, etc.). Three operating modes are included: (1) DC operation at low light levels, (2) pulse detection operation at high peak currents, and (3) single electron counting with cascaded V-plate and Z-plate MCPs.

  • The Behavior of "Magnetic" Electron Multipliers as a Function of Frequency

    This paper consists of a theoretical and experimental study of the frequency variation of gain of magnetic electron multipliers. It is shown that, for multipliers of the type studied, the behavior as a function of over-all electron transit angle is very similar to that observed for electrostatic electron multipliers previously described. Up to frequencies of about 500 megacycles, loss in gain can be ascribed to a spread in transit angle resulting from the emission velocities of secondary electrons and the varying paths of electrons through the stages of the multiplier. From the results given, it is possible to predict the useful upper frequency limit of a magnetic electron multiplier of the type studied.

  • New Developments in Radiation Detectors and Electron Multipliers

    This paper describes several electron devices for the detection of radiation. Discussed are a photomultiplier for UV and X-ray spectrum analysis which uses a switchable segmented photocathode; a large area scintillation counter tube which uses a large size multiplier structure giving it high coupling factor and high current capability; and a small, two terminal electron multiplier structure which uses an inclined strip of semiconductor material in an electric field. Illustrations and some performance data are given.

  • Planar Dynode Multipliers for High-Speed Counting

    The WX 30006 and WX 5009, whose characteristic are summarized in Table I, are just two representatives of a whole family of high-speed tubes which can be constructed using the building blocks at hand. Many trade offs ar possible allowing one to design a tube tailore to a specific application. All tubes incorporating planar dynode multipliers have several features in common, some of which are enumerate below: 1. Uniform and close spacing of dynodes in a plane parallel geometry, combined with high voltage per stage, allowing a substantial reduction in transit time fluctuations as wel as total transit time. 2. Absence of positive ion feedback (owing to the compartmentalized structure of the tube) resulting in virtual eliminatio of after pulses. 3. Ability to operate in the presenc of relatively intense magnetic fields because of the close spacings, high voltages, and guardring effect of the kovar mounting flanges. All TSE tubes have operated effectively in axial fields in excess of 1200 gauss, and there is no reason to suspect that the gain would suffe appreciably even in axial fields of 20 Kilogauss. There are, however, two possible limitation n the usefulness of these tubes which frankly require further investigation: 1. At present the life of these devices is only imperfectly understood. 2. The high voltage required for operating these tubes will in many cases pose problems which require some imagination for their solution.

  • The use of the continuous resistive channeltron ® electron multiplier in optical detectors

    A new optical-detector has been developed which employs a Channeltron multiplier as the electron-multiplying element. The Channeltron multiplier, which is now extensively usod in space-applications to detect charged particles and low-energy radiation in open-window detectors, has been coupled in a vacuum tube with a photocathode responsive to visible and near- ultraviolet radiation. The result is a small, high-gain, low-noise, highly sensitive, extended-red-responsive S-20 photomultiplier tube. The overall length of the tube is about 2 inches, and its diameter is about 1 inch. Only four electrical connections are required. The photocathode, which is processed externally with respect to the tube-envelope, is masked-off so that only a circular area 1 mm in diameter is used. Freedom from excessive alkali vapors, the small photocathode-area, and the inherently-quiet Channeltron electron- multiplier enable the tube to operate at room-temperature with dark-counts on the order of 10 counts/secord or fewer. Magnetic fields and electrostatic fields have little effect on tube-performance. Gains in excess of 107are readily obtainable.

  • Quantum Efficiency Measurements of Windowless Electron Multipliers to Heavy High Energy Particles

    Measurements of quantum efficiency to heavy charged particles, in particular to the proton, in the range of 5 to 2 MeV were made with windowless electron multipliers Qn cathodes of beryllium oxide and aluminum oxide. The effects of oxide thickness on quantum efficiency were determined and some qualitative explanations have been made based on the simple ionization process and escape probability of produced electrons. Using a Van de Graaff accelerator at beam currents of lnA to 5nA, precisions of measurement of better than 10% were obtainable with six different cathodes: three different thicknesses of BeO and three of Al2O3 respectively.

  • Sealed gas UV-photon detector with a multi-GEM multiplier

    A sealed gas photon detector with a gas electron multiplier (GEM) cascade coupled to a semitransparent CsI photocathode has been studied. High gains, reaching 10/sup 6/, and fast anode signals, of a width of 15 ns, were obtained with this GEM-photomultiplier in Ar-CH/sub 4/ (95/5), in a photon counting mode. The lifetime of this first prototype detector under high photon flux and large anode currents is provided.

  • The research of high detection efficiency boron lined detector with a honeycomb neutron converter

    We proposed a new design of a boron lined neutron detector with separated neutron converter and electron multiplier to simplify the manufacturing process. The comprehensive simulations about the detection efficiency have been performed with the aid of MCNP5, Maxwell and Garfield. The neutron detection efficiency with one row of detector unit could achieve 47%@25.3meV with the natB layer and can reach up to 80%@25.3meV with five rows of detector units, implying that this detector could be used in the applications of small- angle neutron scattering for scientific research or radiation portal monitor for homeland security.

Gas Electron Multipliers (GEMs) are being studied as a gas amplification system of TPCs. Recent results from R&D activities with GEM-TPC prototypes ongoing at DESY will be presented. The main focus will be on reconstruction methods and techniques and the spatial resolution that can be achieved.
