    Abstract: A method of manufacturing a photomultiplier tube (10) comprising a tube body (20), a photocathode (30) and an electron multiplier element (40) destined to be placed at a small distance from the photocathode (30). According to the invention the tube (10) is provided with sliding means (50) of the electron multiplier (40) parallel to the axis (22) of the tube body (20), means (50) provided with abutments (53) situated in the proximity of the said window (31). The electron multiplier (40) is also provided with means (60) for the remote soldering of the electron multiplier to the said sliding means (50), and in a first step the electron multiplier (40) is placed at a sufficient distance from the window (31), then in a second step the constituents of the photocathode are evaporated by means of evaporators (70) placed at a distance from the window and, in a third step, the electron multiplier (40) is moved against the said abutments (53), while in a fourth step the electron multiplier (40) is maintained in position in the proximity of the photocathode (30) by remote soldering to the sliding means (50) with the aid of the remote soldering means (60).
