A new automated method has been developed with the aim to correct measured spectra for sudden gain and offset drifts due to temporal instrumentation instabilities. It is based on discrete cross-correlation that alleviates the need for Gaussian-shaped peaks and is capable of correcting spectra that change their shape in time. Potential of this method has been tested on decay and in-beam $\gamma$-ray spectroscopy data measured with an array of three n-type coaxial High-Purity Germanium detectors albeit its use is not limited only for $\gamma$-ray spectroscopy.

受时间不稳定性影响的光谱数据离线校正的自动化方法

已经开发了一种新的自动化方法，旨在校正由于临时仪器不稳定性而导致的突然增益和失调漂移的测量光谱。它基于离散互相关，可减轻对高斯形峰的需要，并能够校正随时间变化其形状的光谱。该方法的潜力已通过衰减和光束测试$\gamma$用三个n型同轴高纯锗探测器阵列测量的X射线光谱数据，尽管其用途不仅限于$\gamma$射线光谱学。
