Abstract
We tested the effects of magnetic fields on a photomultiplier tube (PMT), namely, Hamamatsu R7081, with a large surface area photocathode. The output signals of the PMT were affected in such a way that the magnetic fields deflected photoelectrons to the first dynode. We measured the effects produced by the orientation of the PMT relative to the magnetic fields and the variations in the output signals with respect to the incident light positions in the magnetic fields.
