We present a study of magnetic fields effects on the position resolution and energy response of hyper-pure germanium detectors. Our results provide realistic estimates of the potential impact on the resolving power of tracking-arrays from (fringe) magnetic fields present when operating together with large spectrometers.

By solving the equations of motion for the electron and holes in the presence of both electric and magnetic fields, we analyzed the drift trajectories of the charge carriers to determine the deviations in the positions at the end point of the trajectories, as well as changes in drift lengths affecting the energy resolution and peak shift due to trapping. Our results show that the major effect is in the deviation of the transverse (to the electric field direction) position and suggest that, if no corrective action is taken in the pulse-shape and tracking data analysis procedures, a field strength $\gtrsim$ 0.1 T will start to impact the intrinsic position resolution of 2 mm (RMS). At fields above $\sim$1 T, the degradation of the energy response becomes observable.

我们目前研究磁场对超纯锗探测器的位置分辨率和能量响应的影响。我们的结果提供了对与大型光谱仪一起运行时（边缘）磁场对跟踪阵列分辨能力的潜在影响的现实估计。

通过求解存在电场和磁场的情况下电子和空穴的运动方程，我们分析了电荷载流子的漂移轨迹，以确定在轨迹终点位置的偏差以及其变化。漂移长度会影响能量分辨率和由于陷获而引起的峰位移。我们的结果表明，主要影响在于横向（相对于电场方向）位置的偏差，并且表明，如果在脉冲形状和跟踪数据分析程序中未采取纠正措施，则磁场强度$\gtrsim$0.1 T将开始影响2 mm（RMS）的固有位置分辨率。在上方的字段$〜$在1T时，可以观察到能量响应的下降。
