A high-purity germanium detector flicker noise measuring device

Abstract

The utility model discloses a kind of high-purity germanium detector microphonic noise measuring devices, including detector body and tremble noise detection component, the tremble noise detection component is installed on the surface of detector body;The tremble noise detection component includes several tremble noise detection modules, each tremble noise detection module is respectively arranged at the top, bottom and circumferential side of detector body;The tremble noise detection module includes vibration accelerometer and voice coil motor, vibration accelerometer and voice coil motor are all installed at the surface of detector body place.This device is by being provided with tremble noise detection module in multiple positions of high-purity germanium detector, different orientation tremble noise data can be detected, by analyzing each tremble noise data, explore the influence law of different position different vibration amplitude of high-purity germanium detector on detector microphonic noise, study the mechanism of high-purity germanium detector microphonic noise generation, provide technical guidance for electric refrigeration high-purity germanium detector microphonic noise suppression, solve the pain point problem of poor resolution of electric refrigeration high-purity germanium detector.
