Abstract: A waveform shaping filter according to an embodiment includes at least one filter stage and a control circuit. The filter stage includes a differentiation signal generation circuit, a proportional signal generation circuit, and an adder circuit. The differentiation signal generation circuit generates a differentiation signal obtained by amplifying a differentiation component of an input signal. The proportional signal generation circuit generates a proportional signal obtained by amplifying the input signal. The adder circuit outputs an output signal obtained by adding the proportional signal and the differentiation signal. The control circuit compares the output signal and a first detection level, detects at least one of an overshoot and an undershoot of the output signal, and controls a time constant of the filter stage, based on a detection result.

Abstract: According to an embodiment, a photon detector includes a photoelectric converter, a voltage supplier, a potential variation detector, and an adjustor. The photoelectric converter performs photoelectric conversion based on an incident photon and outputs current corresponding to number of photons. The voltage supplier supplies a voltage to the photoelectric converter. The potential variation detector detects potential variation of a cathode of the photoelectric converter. The adjustor adjusts a potential of an anode of the photoelectric converter based on the potential variation detected by the potential variation detector so that variation in a potential difference between the cathode and the anode of the photoelectric converter is reduced, and outputs current from the photoelectric converter to the outside.
