    Abstract: A photomultiplier tube (10) for the use in high collecting power is described having a photocathode (20), a first dynode (30) and a stackable-dynode multiplier device (40). According to the invention, the first dynode (30) is constituted by a sheet which extends parallel to the photocathode (20) and is provided with a feedthrough aperture (31), an extracting grid (32) being arranged between the photocathode (20) and the sheet, and the stackable-dynode multiplier device (40) is positioned opposite the aperture (30) in such a manner as to collect the secondary electrons (50) emitted by the first dynode (30) and passing through the feedthrough aperture (31).

    Abstract: A photomultiplier tube which is insensitive to high magnetic fields comprises a photocathode deposited on a transparent window at the end of an insulating casing. The multiplier tube comprises a single amplifier stage comprising a dynode. The dynode is a metallic sheet with a circumference substantially surrounding the photocathode. A layer of a secondary emissive material is provided on the inner face of the dynode. An anode is formed of a metallic grid which is homeomorphous to the surface of the dynode. The anode is placed parallel to and at a short distance from the inside surface of the dynode.
