摘要
弯曲的单体活性像素传感器是计划中的全圆柱形超低材料预算跟踪探测器 ITS3 的基础。本文 presenting了使用高能粒子进行的测试束阵营测试结果，以验证 50 um 厚度弯曲 ALPIDE 芯片在效率和空间分辨率方面的性能。传感器弯曲至 18、24 和 30 mm 的曲率半径，略小于未来 ALICE ITS3 层预见的弯曲曲率半径。在 nominal operating 条件下，获得超过 的效率和约 5 um 的空间分辨率，这与平坦 ALPIDE 传感器的 nominal operation 条件相符。这些值随弯曲曲率半径而独立，从而构成了计划 ITS3 探测器可行性的额外里程碑。此外，还研究了一种特殊几何形态，其中束流粒子在芯片上轻微 grazing 并横向穿过最长达 3 mm 的距离。
