Title:
PHOTOMULTIPLIER TUBE
Document Type and Number:
WIPO Patent Application WO/2010/142064
Kind Code:
A1
Abstract:
A photomultiplier tube comprises a photocathode (14), an electron multiplier (10), an electron collector (11) and a power lead (12), wherein the photocathode (14) and the electron multiplier (10) are disposed in a sealed transparent vacuum envelope (8), the electron collector (11) and the power lead (12) are connected with an external circuit outside the vacuum envelope (8), the photocathode (14) is formed on the entire inner surface of the vacuum envelope (8), and the electron multiplier (10) is located on the center of the vacuum envelope (8) to receive photoelectrons from the photocathode (14) in all directions for electron multiplication. Because the effective area of the photocathode is increased, the detection efficiency of unit light-receiving area is improved.
