Photomultiplier amplifier and power supply

Claim 1

IN A LASER POWER SUPPLY SYSTEM, THE COMBINATION WITH A PHOTOMULTIPLIER DEVICE HAVING AN ANODE, A CATHODE AND A SERIES OF DYNODES SPACED APART BETWEEN SAID ANODE AND CATHODE, OF A PLURALITY OF VOLTAGE SUPPLY CAPACITORS CONNECTED IN SERIES BETWEEN SAID ANODE AND CATHODE, A LONG-TIME-CONSTANT DISTRIBUTION NETWORK INCLUDING A PLURALITY OF SERIES-CONNECTED RESISTORS CONNECTED BETWEEN THE SAID ANODE AND CATHODE IN PARALLEL RELATION TO SAID CAPACITOR SERIES, MEANS CONDUCTIVELY INTERCONNECTING THE SUCCESSIVE DYNODES WITH THE SUCCESSIVE CAPACITOR JUNCTIONS AND RESISTOR JUNCTIONS IN THE PARALLEL CONNECTED CAPACITOR AND RESISTOR SERIES, A PLURALITY OF ISOLATION DIODES, A STORAGE CAPACITOR HAVING A HIGH-VOLTAGE SUPPLY CIRCUIT COUPLED THEREWITH FOR CHARGING SAID CAPACITOR IN RESPONSE TO APPLIED SUPPLY VOLTAGES ABOVE A PREDETERMINED LEVEL, A SHORT-TIME-CONSTANT DISTRIBUTION NETWORK INCLUDING A PLURALITY OF SERIES-CONNECTED RESISTORS EQUAL IN NUMBER TO THE FIRST NAMED RESISTORS AND COUPLED THEREWITH IN PARALLEL RELATION INDIVIDUALLY THROUGH SAID ISOLATION DIODES FOR CHARGING SAID CAPACITORS IN RESPONSE TO CHARGING OF SAID STORAGE CAPACITOR TO SAID VOLTAGE LEVEL, AND MEANS COUPLING SAID SHORT-TIME-CONSTANT NETWORK IN PARALLEL RELATION WITH SAID STORAGE CAPACITOR FOR APPLYING AN OUTPUT VOLTAGE ABOVE A PREDETERMINED LEVEL TO SAID DISTRIBUTION NETWORKS AND CAPACITOR SERIES.
