Claim:
1. A device for processing data delivered by a photon detector, comprising: a first analog circuit capable of generating, on a first node, a first signal having a series of pulses, each pulse having an amplitude proportional to energy released by an interaction of a photon in the photon detector; a second analog circuit configured to provide a second signal switching from a first state to a second state upon detection of a decrease of the amplitude of the first signal; and a capture element comprising a plurality of capacitors and a plurality of write switches, each capacitor of the plurality of capacitors having a first electrode connected to the first node via a write switch of the plurality of write switches and a second electrode connected to a node of application of a reference voltage, the capture element further comprising a control circuit configured to receive the second signal, the control circuit being capable of controlling the write switches to record a value of the first signal into one of the capacitors when the second signal switches from the first to the second state.
