| Bismuth germinate crystal, that is Bi4Ge3O12, in short, BGO, is a very excellent multifunctional scintillator. BGO crystal has many advantages, for example, it has a strong point in preventing radial and is highly efficient (the highest efficiency in detecting gamma-rays at present), at the same time, its deliquescence is unlikely and its Mechanical quality is very high. So it is widely used in high-energy physics,nuclear physics,space physics and other industry fields.But BGO has also a great weakness that the transformation efficiency of its fluorescence is susceptible to temperature, and this will lead to the instability of the whole system and then the error will arise, Consequently,the precision and the reliability will decrease.In this instance, a temperature-controlled setup is developed, which is aimed at peak-shifting in energy spectrum and changing in energy resolution caused by changing in temperature when BGO detector is used to detect the gamma-rays in experiment. And we have a research in the temperature characteristic of BGO crystal; this study will also play a guidance role in other fields. In this article, the study is introduced. |
