摘要： PROBLEM TO BE SOLVED: To provide a photo-detector and a method for operating the same.SOLUTION: The photo-detector comprises: a photomultiplier tube comprising a plurality of electrodes, each having a photocathode, an anode, a first dynode, intermediate dynodes and a last dynode; and a biasing circuit that comprises a sequence of voltage follower elements, a voltage divider and a current source. The voltage divider is coupled to both ends of a high voltage power supply and different dynodes are coupled to different ones of the voltage follower elements, control inputs of the voltage follower elements being coupled to different junctions of the voltage divider. The current source is coupled to the voltage divider, to the sequence of the voltage follower elements and to the cathode. The anode is coupled to a load element coupled to a positive pole of the high voltage power supply and arranged to receive an output signal of the anode and convert it to an output signal of the photo-detector.
