    • PURPOSE:To obtain a photomultiplier tube that performs stable operation even in a relatively large magnetic field by setting the length from a photoelectric surface to the first step of a multi-step mesh dynode and the gap between the respective mush dynodes to the specified range. CONSTITUTION:Mesh dynodes Dyl to Dy8 are comprised with a number of rods B whose secondary electron emission surfaces are formed on the surfaces that are mutually arranged in parallel and a mesh-type field formation electrode M secured to the photoelectric PC side. Besides, an anode A is made of a mesh- type electrode and a plate-type final step dynode Dy9 forms a secondary electron emission surface at the anode A side. In addition, the length from a photoelectric surface 9C to the first step Dy1 of a multi-step mesh dynode is set within the range from 1/15 to 1/5 of the diameter of the photoelectric surface or the diameter of the inscribed circle of a square-type photoelectric surface. Furthermore, the gap between the respective mesh dynodes Dy1, gap between the final step mesh dynode Dy8 and anode A, and gap between the anode A and plate-type final step dynode Dy9 are smaller than the length from the photoelectric surface PC to the first step Dy1 of the mesh dynode.
