Title:
PHOTOMULTIPLIER TUBE
Document Type and Number:
WIPO Patent Application WO/2007/020741
Kind Code:
A1
Abstract:
Provided is a photomultiplier tube having a fine structure for achieving a high multiplication
efficiency. The photomultiplier tube is provided with an envelop inside of which
is kept in a vacuum state, and on a device mounting plane (40a), which is a part of
an inner wall plane defining the inner space of the envelop, a photocathode (22)
which is of reflective type, an electron multiplication section (31), an anode
(32) and a voltage distributing section (311) are arranged. Especially, the
electron multiplication section is composed of a plurality of steps of dynodes for
performing cascade multiplication of photoelectrons from the photocathode. The
voltage distributing section for applying corresponding voltages to the steps
of dynodes, respectively, is on the same plane with the electron multiplication section.
