AN INVESTIGATION OF THE RESPONSE OF PHOTOMULTIPLIER TUBES. Period covered: Setpember 1957 to August 1958

Technical Report ·
OSTI ID:4076923

The response of a photomultiplier tube is related to its average sensitivity and can be improved by using only the most sensitive part of the photocathode. A number of graphs are presented to illustrate the response of a photomultiplier tube as a function of the point on the photocathode surface that is illuminated and to indicate the improvement in symmetry of the isosensitivity lines that may be achieved by varying the shield voltage. While the observed sensitivities were due primarily to the geometry of the cathode-dynode configuration, they were also due partially to the nonuniform response of the cathode surface. (auth)
