摘要
本文论述了13N监测仪中的谱漂移和稳谱问题,给出了实验测量方法及测量原理框图,并对谱仪系统的能量与温度的非线性关系进行了测量;采用非线性方法稳谱,温度在10—45℃范围内变化时,511keVγ光子的峰位道址漂移小于±1道。
Problems of spectrum-drifting and spectrum stabilization in the 13N monitoring instrument were discussed and the measuring principle including block-diagram was given. The nonlinear relationship between the energy and temperature was measured. As the non-linearity method is applied, the 511 keV γ-ray’s peak location drifts only <±1 channel for the temperature change from 10℃ to 45℃.
