  • Performance studies of a new Russian FEU115M phototube
    IEEE Transactions on Nuclear Science, 1995
    Co-Authors: G. David, S. Stoll, E Kistenev, S. N. White, C. L. Woody
    Abstract:

    We report on the results of tests of FEU115M one inch Phototubes manufactured in Russia. The tubes are 12-stage, fast devices with high gain and low dark current. These photomultiplier tubes were developed for the PHENIX EMCal project by members of the PHENIX group at IHEP, Protvino (Russia). We report on investigations of the gain, quantum efficiency, linearity, photocathode uniformity and long-term behavior of these tubes.

  • The SELEX phototube RICH detector
    Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 1999
    Co-Authors: Jürgen Engelfried, I. S. Filimonov, J. Kilmer, A. P. Kozhevnikov, V. P. Kubarovsky, V. V. Molchanov, A. V. Nemitkin, E. J. Ramberg, V. Rud, L. Stutte
    Abstract:

    Abstract In this article, construction, operation, and performance of the RICH detector of Fermilab experiment 781 (SELEX) are described. The detector utilizes a matrix of 2848 Phototubes for the photocathode to detect Cherenkov photons generated in a 10 m neon radiator. For the central region an N 0 of 104 cm −1 , corresponding to 13.6 hits on a β =1 ring, was obtained. The ring radius resolution measured is 1.6%.

  • A phototube RICH detector
    Nuclear Instruments and Methods in Physics Research Section A: Accelerators Spectrometers Detectors and Associated Equipment, 1993
    Co-Authors: M. Pommot Maia, I. S. Filimonov, L. Stutte, P. S. Cooper, V. Solyanik, A. V. Nemitkin
    Abstract:

    Abstract The results from a prototype for a fast RICH detector using Phototubes are presented, testing three different types of tubes in the photocathode. In a 400 GeV/ cπ − beam, the number of photons detected was 11.8 per ring and the ring radius resolution obtained was 1.13%. The figure of merit, N 0 , for the entire photocathode was measured to be 93/cm. Particle identification as a function of beam momentum was studied, as well as multiparticle event recognition.

  • Evolution of ideas in photon detection
    Physics of Particles and Nuclei, 2016
    Co-Authors: B.k. Lubsandorzhiev
    Abstract:

    In this paper we consider an evolution of ideas in vacuum photodetector developments. Diverse approaches in developments of vacuum photodetectors (classical photomultipliers and hybrid Phototubes) for the last half of century are covered. A particular emphasis is made on large area vacuum photodetectors developments. Some other issues concerning WLS and light guide techniques for increasing photodetectors sensitivity are highlighted as well.

    Abstract:

    In this paper we review hybrid Phototubes with luminescent screens used in deep underwater neutrino telescopes.

  • The Quest for the Ideal Scintillator for Hybrid Phototubes
    IEEE Transactions on Nuclear Science, 2008
    Co-Authors: B.k. Lubsandorzhiev, B. Combettes
    Abstract:

    In this paper we present the results of extensive studies of scintillators for hybrid Phototubes with luminescent screens. The results of the developments of the Phototubes with a variety of scintillators are presented. New scintillator materials for such kind of application are discussed. The requirements for scintillators to use in such hybrid Phototubes are formulated. It is shown that very fast and highly efficient inorganic scintillators like ZnO:Ga will be ideal scintillators for hybrid Phototubes with luminescent screens.

  • Photoelectron backscattering in vacuum Phototubes
    Nuclear Instruments and Methods in Physics Research Section A: Accelerators Spectrometers Detectors and Associated Equipment, 2006
    Co-Authors: B.k. Lubsandorzhiev, R. V. Vasiliev, Y. E. Vyatchin, B. A. J. Shaibonov
    Abstract:

    Abstract In this article we describe results of studies of a photoelectron backscattering effect in vacuum Phototubes: classical photomultipliers (PMT) and hybrid Phototubes (PH). Late pulses occurring in PMTs are attributed to the photoelectron backscattering and distinguished from pulses due to an anode glow effect. The late pulses are measured in a number of PMTs and HPs with various photocathode sizes covering 1–50 cm range and different types of the first dynode materials and construction designs. It is shown that the late pulses are a generic feature of all vacuum photodetectors—PMTs and PHs—and they do not deteriorate dramatically amplitude and timing responses of vacuum Phototubes.
