Abstract : An improvement for a photomultiplier tube having its cathode, dynodes and anode spaced apart within an envelope increases the tube's linear dynamic range capability. A constant and stable collection potential is maintained between the anode and the dynode nearest the anode. In one form a zener diode voltage source and serially connected resistor are used or a fixed voltage is appropriately connected separate and distinct from the dynode potential connected across the other dynodes and the cathode. Thusly modified, a light flux range of approximately eight orders of magnitude can be accommodated by the improved photomultiplier tube circuitry. (Author)
