Gain control device, system and method for silicon photomultiplier

Abstract

The invention relates to a gain control device, a gain control system and a gain control method for a silicon photomultiplier. The gain control device is used for controlling gain of the silicon photomultiplier which is connected in series with the gain control device. The gain control device comprises a controllable voltage source and at least one voltage stabilizing diode which are connected in series, wherein the controllable voltage source comprises at least one input terminal; the voltage stabilizing diode works in a breakdown state; an equivalent temperature coefficient of the voltage stabilizing diode is the same as a temperature coefficient of the silicon photomultiplier; the gain of the silicon photomultiplier is controlled by regulating voltage on the input terminal of the controllable voltage source. A technical scheme adopted by the invention is simple, uses fewer components and parts, and can realize temperature compensation by only needing to use an analog device, so that a temperature sensor, a corresponding digital unit and a corresponding feedback system are cancelled, and the reliability of the system is increased.
