ABSTRACT:
A photomultiplier includes a cathode supporting member, arranged in a tube and comprised of a conductive material, for holding a photocathode, and a holding mechanism, comprised of a heat conductive material, for biasing the cathode holding member to hold it. The holding mechanism is thermally connected to a cooler.
