摘要:

为了应对高亮度大型强子对撞机的恶劣条件,ATLAS内部跟踪器必须进行升级,以满足辐射硬度、堆积和几何验收方面的要求。有源边缘技术可减少传感器边缘的不敏感区域,这要归功于离子蚀刻沟槽,避免了标准机械切割工艺产生的晶体损伤。LPNHE和FBK代工厂设计并生产了具有有源边缘的薄型平面n-on-p像素传感器。两个探测器模块原型,由连接到FE-I4 B读出芯片的像素传感器组成,已经在CERN和DESY进行了光束测试。在本文中,这些模块的性能报告。特别是横向延伸的检测体积,超出像素区域,进行了研究,结果表明高命中效率也在检测器边缘,即使在保护环的存在下。

英文摘要:

To cope with the High Luminosity LHC harsh conditions, the ATLAS inner tracker has to be upgraded to meet requirements in terms of radiation hardness, pile up and geometrical acceptance. The active edge technology allows to reduce the insensitive area at the border of the sensor thanks to an ion etched trench which avoids the crystal damage produced by the standard mechanical dicing process. Thin planar n-on-p pixel sensors with active edge have been designed and produced by LPNHE and FBK foundry. Two detector module prototypes, consisting of pixel sensors connected to FE-I4B readout chips, have been tested with beams at CERN and DESY. In this paper the performance of these modules are reported. In particular the lateral extension of the detection volume, beyond the pixel region, is investigated and the results show high hit-efficiency also at the detector edge, even in presence of guard rings.
