使用FE-I4A前端读出芯片的ATLAS IBL模块原型

Prototype ATLAS IBL Modules using the FE-I4A Front-End Readout Chip

The ATLAS IBL Collaboration

摘要:

ATLAS合作将升级其半导体像素跟踪探测器,在现有的像素探测器和大型强子对撞机的真空管之间安装一个新的可插入B层(IBL)。该位置的极端工作条件需要开发新的辐射硬像素传感器技术和新的前端读出芯片FE-I4。平面像素传感器和3D像素传感器已被研究,以装备这种新的像素层,并使用FE-I4 A原型模块已被制造和表征,使用120 GeV的π介子在欧洲核子研究中心SPS和4 GeV的正电子在DESY,模块照射前后。给出了束流测试结果,包括电荷收集效率、跟踪效率和电荷共享。

英文摘要:

The ATLAS Collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing pixel detector and the vacuum pipe of the Large Hadron Collider. The extreme operating conditions at this location have necessitated the development of new radiation hard pixel sensor technologies and a new front-end readout chip, called the FE-I4. Planar pixel sensors and 3D pixel sensors have been investigated to equip this new pixel layer, and prototype modules using the FE-I4A have been fabricated and characterized using 120 GeV pions at the CERN SPS and 4 GeV positrons at DESY, before and after module irradiation. Beam test results are presented, including charge collection efficiency, tracking efficiency and charge sharing.
