Abstract

The Ceramic Electron Multipliers (CEM) is a compact, robust, linear and fast multi-channel electron multiplier. The Multi Layer Ceramic Technique (MLCT) allows to build metallic dynodes inside a compact ceramic block. The activation of the metallic dynodes enhances their secondary electron emission (SEE). The CEM can be used in multi-channel photomultipliers, multi-channel light intensifiers, ion detection, spectroscopy, analysis of time of flight events, particle detection or Cherenkov imaging detectors.

Electron Multipliers Utilizing Continuous Strip Surfaces

Journal Article Wiley, W. C. ; Hendee, C. F. - IRE Transactions on Nuclear Science

Thin films of semiconducting materials with secondary electron emission ratios greater than one have been used for some years in the Bendix crossed electric and magnetic field electron multiplier for ion detection. In these devices, the electric field to accelerate the electrons is established by the potential gradient created by external current flowing through the resistive strip. A low background counting rate, insensitivity to radiation in the visible and near ultraviolet, and stability on exposure to atmospheric gases are properties which permit this device to have interesting photon detection applications in the extreme ultraviolet in dynamic vacuum systems and outermore »« less

Gain of a continuous channel electron multiplier in magnetic fields (in Japanese)

Journal Article Otsuji, T - Kobe Shosen Daigaku Kiyo. Dai-2-rui. Kokai, Kikan,, no. 20, pp. 231- 237

Gain of a helical continuous channel electron multiplier, operated under the existence of extennal magnetic fields, was measured. When the intensity of the magnetic field was increased in one direction (this direction was regarded as a negative direction), the gain increased and then began to decrease. On the other hand, when the magnetic field was applied in an opposite direction (positive direction), the gain decreased and attained the minimum. A further increase of the field in this direction showed the similar behavior in the case of the negative magnetic field. The slope of the magnetic flux density versus the gainmore »« less
THE CHANNELED SHAPED-SCREEN IMAGE INTENSIFIER

Technical Report Burns, J ; Neumann, M J

The present status of the channeled, shaped-screen intensifier may be summarized as follows: the principle offers certain characteristic advantages over other types of intensifiers, the chief ones being resolution independent of the number of stages, low voltagc operation with the attendant possibility that background levels will be low, and the possibility, depending on design requirements of the photocathode, that the screens can be made to support the atmospheric pressure on thin faceplates, making the construction of large-area tubes a possibility. Thus far a dynode design has been devised which has yielded gains per stage equal to about 75% of themore »« less
Transit time spread measurements of microchannel plate photomultipliers

Conference Keskovar, B ; Lo, C C

An investigation of the single photoelectron and multi-photoelectron transit time-spread performance of prototype photomultipliers using curved high-gain microchannel plates for electron multiplication and proximity focusing for the input and collector stages is reported. A microchannel plate consists of a closely packed two dimensional array of very small diameter, short channel-electron multipliers. Each single channel electron multiplier is a continuous glass tube whose inside surface has a high resistance semiconducting coating used a a secondary electron-emitting surface. Measurement of the transit time spreads of the HR350 and HR400 photomultipliers (made by the Laboratories d'Electronique et the Physique Appliquee) using a speciallymore »« less

Performance characterization of high quantum efficiency metal package photomultiplier tubes for time-of-flight and high-resolution PET applications

Journal Article Ko, Guen Bae ; Lee, Jae Sung, E-mail: jaes@snu.ac.kr ; Department of Biomedical Science, Seoul National University College of Medicine, Seoul 110-744 ; ... - Medical Physics

Purpose: Metal package photomultiplier tubes (PMTs) with a metal channel dynode structure have several advanced features for devising such time-of-flight (TOF) and high spatial resolution positron emission tomography (PET) detectors, thanks to their high packing density, large effective area ratio, fast time response, and position encoding capability. Here, we report on an investigation of new metal package PMTs with high quantum efficiency (QE) for high-resolution PET and TOF PET detector modules. Methods: The latest metal package PMT, the Hamamatsu R11265 series, is served with two kinds of photocathodes that have higher quantum efficiency than normal bialkali (typical QE ≈ 25%),more »« less
