论文摘要
在测试光束中测试和校准粒子探测器时，在数据离线分析期间，准确的跟踪信息独立于被测试的检测器非常有用。用32.0 x 32.0 mm2的活性面积构建了通用硅光束追踪器（SBT），以提供此能力，以用于宇宙射线能量和质量（奶油）热量表的光束校准。跟踪器由两个模块组成，每个模块由两个正交层组成380μm厚的硅条带传感器。在一个模块中，每层是一个64通道AC耦合的单面硅条检测器（SSD），其螺距为0.5 mm。另一层是32通道DC耦合的单面SSD，其螺距为1.0 mm。使用改良的奶油霍迪镜前端电子设备将四层信号读取，并带有USB 2.0接口板到Linux DAQ PC。在本文中，我们介绍了SBT的构建，以及其在放射性源测试中的性能以及2006年10月的CERN Beam测试。
When testing and calibrating particle detectors in a test beam, accurate tracking information independent of the detector being tested is extremely useful during the offline analysis of the data. A general-purpose Silicon Beam Tracker (SBT) was constructed with an active area of 32.0 x 32.0 mm2 to provide this capability for the beam calibration of the Cosmic Ray Energetics And Mass (CREAM) calorimeter. The tracker consists of two modules, each comprised of two orthogonal layers of 380 μm thick silicon strip sensors. In one module each layer is a 64-channel AC-coupled single-sided silicon strip detector (SSD) with a 0.5 mm pitch. In the other, each layer is a 32-channel DC-coupled single-sided SSD with a 1.0 mm pitch. The signals from the 4 layers are read out using modified CREAM hodoscope front-end electronics with a USB 2.0 interface board to a Linux DAQ PC. In this paper, we present the construction of the SBT, along with its performance in radioactive source tests and in a CERN beam test in October 2006.
