ATLAS SLHC像素探测器的金刚石原型
Diamond Prototypes for the ATLAS SLHC Pixel Detector
摘要：
未来强子对撞机的顶点探测器将需要处理大粒子注量。金刚石是一种特别抗辐射的材料，并表现出进一步的特性，使其成为这种探测器的有吸引力的材料。在RD42合作中，正在研究几种化学气相沉积金刚石样品，其形式为条带和像素探测器。虽然多晶金刚石样品的质量不断提高，生产晶片的可行性也得到了证明，但最近在CERN组装了单晶金刚石像素探测器，并在100 GeV粒子束中进行了表征。性能，检测效率，空间分辨率和电荷收集的结果一起报告在这里与最新的辐射损伤研究。
英文摘要：
Vertex detectors at future hadron colliders will need to cope with large particle fluences. Diamond is a particularly radiation hard material and exhibits further properties that makes it an attractive material for such detectors. Within the RD42 collaboration several chemical vapor deposition diamond samples are being studied in the form of strip and pixel detectors. While the quality of the poly-crystalline diamond samples is constantly increasing and the feasibility of producing wafers has been demonstrated, recently a single-crystal diamond pixel detector has been assembled and characterized in a 100 GeV particle beam at CERN. Results on performance, detection efficiency, spatial resolution and charge collection are reported here together with the latest radiation damage studies.
