  • Patent number: 7786671
    Abstract: A single-channel photomultiplier tube having a sealed envelope, of which one wall includes an internal face having a concavity with a central axis, turned toward the inside of the tube, having a plane of symmetry and containing a photocathode, inlet optics including electrodes, an electron multiplier including a plurality of dynodes, an anode, and a mechanism connecting the dynodes, the photocathode, electrodes of the optics, and the anode, at their respective operating voltages. The electron multiplier is composed of parts physically distinct from one another, and having between them a symmetry of revolution with respect to the central axis of the concavity.

  • Publication number: 20080258619
    Abstract: Single-channel photomultiplier tube (1) having a sealed envelope (4), of which one wall (5) comprises an internal face (7) having a concavity with a central axis (AA?), turned toward the inside of the tube, having a plane of symmetry and containing a photocathode (2), inlet optics (9) comprising electrodes, an electron multiplier (11) comprising a plurality of dynodes (30-39), an anode (16), means (12) for connecting the dynodes (30-39), the photocathode (2), electrodes (13, 15) of the optics (9), and the anode (16), at their respective operating voltages, characterised in that the electron multiplier is composed of parts (24, 26) physically distinct from one another, and having between them a symmetry of revolution with respect to the central axis of concavity.
