Abstract

The design of the straw tube tracker (STT) is described. The detector consists of 48 sectors and an overall of 11,000 straws, which allows precise track measurements in the forward direction of the ZEUS-detector at HERA. Test beam measurements are shown and the results are compared to Monte Carlo simulations. The STT is also used in the ZEUS trigger logic. An offline reconstruction algorithm is implemented and works. It is shown that we are able to reconstruct tracks in the forward direction of ZEUS, up to a pseudorapidity of 3.2 with high efficiency.

HERA zeus探测器的吸管管跟踪器

介绍了秸秆管跟踪器的设计。探测器由48个扇形部分和总共11,000个吸管组成，这使得HERA的zeus探测器可以在前进方向上进行精确的跟踪测量。给出了测试光束的测量结果，并将结果与蒙特卡罗模拟结果进行了比较。STT也用于ZEUS触发器逻辑。实现了一种离线重构算法，并取得了良好的效果。结果表明，我们能够在ZEUS的前进方向上重建轨迹，伪快度高达3.2，效率很高。
