Definitions

  • Fig. 1 illustrates a photomultiplier tube 10 having a glass envelope 12 (e.g., Kovar-sealing glass envelope).
  • the glass envelope 12 comprises an optical window 14 for optical photons generally designated by OP.
  • the inner surface of the optical window 14 bears a photocathode 16 (e.g. K 2 C 5 ⁇ b with pre-evaporated layer of Sb).
  • a photocathode 16 e.g. K 2 C 5 ⁇ b with pre-evaporated layer of Sb.
  • Inside the glass envelope 12 is also arraned, e.g., by means of insulator elements 18, a position/centroid-determining anode 20.
  • the photomultiplier tube 10 For the voltage supply of the imaging dynodes 26a-26n, the photocathode 16 and the anode 20 (and for other internal processing elements, if desired) the photomultiplier tube 10 comprises lead connections 38 and 40 (e.g., 21-35 Kovar Leads) which connect the aforementioned inner elements with an outer (not shown) voltage supply.
  • An exhaust tubulation of the glass envelope 12 is generally designated by 42.
  • the cones 28'of dynodes 26a'-26n' have cone tips 30 which merge under a flatter angle than the angle of the cone shells.
