摘要
多种因素可能导致径迹探测器传感器对齐的困难，包括大量模块、多种探测器技术类型以及传感器上非线性的条带图案。这三个因素均适用于 CLAS12 CVT，它是一种混合探测器，由具有非平行条带的平面硅传感器，以及位于 5~T 超导螺线管内的具有纵向和弧形条带的圆柱形 micromegas 传感器组成。为对齐该探测器，我们采用了卡尔曼对齐算法（Kalman Alignment Algorithm），该算法考虑了对齐参数之间的相关性，且无需耗时的巨型矩阵求逆。这是该算法首次被改造用于混合技术、非平行条带和弯曲传感器。我们给出了使用来自宇宙射线和磁场关闭时来自靶标的直线径迹对 CLAS12 CVT 进行首次对齐的结果。运行该流程后，我们实现了 10~m 量级的对齐，并且残差谱的宽度大幅减小。这些结果证明了该算法的灵活性及其在未来 CLAS12 CVT 和其他混合或弯曲径迹探测器（例如为未来电子-离子对撞机所提出的那些）中应用的适用性。
