Scintillator High-Voltage Power Supply and Its Application in Nuclear Physics Experiments

A scintillator is a device that uses the fluorescence phenomenon produced by a material when it is irradiated to detect radiation. The scintillator high-voltage power supply is a core component of a scintillator, providing the working voltage for the scintillator to operate normally. The scintillator high-voltage power supply has a wide range of applications in nuclear physics experiments, mainly for the detection of gamma rays, neutrons, and protons.
Basic Principle of Scintillator High-Voltage Power Supply
The basic principle of a scintillator high-voltage power supply is to use the charging and discharging of a capacitor to generate high-voltage current. A scintillator high-voltage power supply generally consists of a power transformer, rectifier circuit, filter circuit, and high-voltage power supply. The power transformer converts the mains voltage to high-voltage voltage, the rectifier circuit converts the high-voltage alternating current to high-voltage direct current, the filter circuit filters out the alternating component of the high-voltage direct current, and the high-voltage power supply outputs the high-voltage direct current to the scintillator.

Scintillator high-voltage power supplies can be divided into the following types according to their working principles and structures:
Capacitor charging and discharging type high-voltage power supply: This type of power supply uses the capacitor charging and discharging principle to generate high-voltage current, with the advantages of simple structure and low cost, but its output voltage is unstable and its efficiency is low.
Inverter type high-voltage power supply: This type of power supply uses inverter technology to generate high-voltage current, with the advantages of stable output voltage, high efficiency, and small size, but its cost is relatively high.
Inductive energy storage type high-voltage power supply: This type of power supply uses the inductive energy storage principle to generate high-voltage current, with the advantages of large output current and short pulse width, but its cost is relatively high.
