摘要:

大型强子对撞机的CMS实验包括一个混合硅像素探测器,用于重建带电轨道和相互作用顶点。筒区由n中n型传感器组成,其单元尺寸为100 × 150 μ m^2,在扩散氧化的浮区硅上加工。偏置网格的实施和像素隔离实现与缓和的p-喷雾技术。在CERN SPS的H2束线上进行了广泛的测试计划。在本文中,我们描述了传感器的布局,光束测试设置和辐照和非辐照原型设备所获得的结果。给出了电荷收集、命中探测效率、洛伦兹角和空间分辨率的测量结果。

英文摘要:

The CMS experiment at the LHC includes a hybrid silicon pixel detector for the reconstruction of charged tracks and of the interaction vertices. The barrel region consists of n-in-n sensors with 100X150 um^2 cell size processed on diffusion oxygenated float zone silicon. A biasing grid is implemented and pixel isolation is achieved with the moderated p-spray technique. An extensive test program was carried out on the H2 beam line of the CERN SPS. In this paper we describe the sensor layout, the beam test setup and the results obtained with both irradiated and non-irradiated prototype devices. Measurements of charge collection, hit detection efficiency, Lorentz angle and spatial resolution are presented.
