FIELD: nuclear physics. SUBSTANCE: photoelectric multiplier has case with optical input window houses dynode system composed of dynodes with circular arrangement. Photocathode is made transparent with conducting plates and is applied on to inner surface of optical input window. Two focusing electrodes are placed along photocathode. Last dynode is produced with at least two electrically insulated sections having independent leads-out. EFFECT: facilitated manufacture, improved operational characteristics. 1 dwg
