摘要:

我们报告的n-对-p,三维双面双列(3D-DDTC)像素探测器的发展FBK-irst(特伦托,意大利)制造和面向ATLAS升级。所考虑的制造技术比具有主动边缘的全3D探测器所需的制造技术更简单,但是探测器效率和辐射硬度关键地取决于柱状电极重叠,并且应该仔细评估。这些传感器(每像素2、3或4列)与ATLAS FEI 3读出芯片的第一批组件已在实验室中进行了测试。选择的结果与放射源的电气和功能特性进行了讨论。

英文摘要:

We report on the development of n-on-p, 3D Double-Side Double Type Column (3D-DDTC) pixel detectors fabricated at FBK-irst (Trento, Italy) and oriented to the ATLAS upgrade. The considered fabrication technology is simpler than that required for full 3D detectors with active edge, but the detector efficiency and radiation hardness critically depend on the columnar electrode overlap and should be carefully evaluated. The first assemblies of these sensors (featuring 2, 3, or 4 columns per pixel) with the ATLAS FEI3 read-out chip have been tested in laboratory. Selected results from the electrical and functional characterization with radioactive sources are here discussed.
