ATLAS IBL像素升级

ATLAS IBL Pixel Upgrade

A. La Rosa

摘要:

ATLAS探测器的升级将经历向超级LHC升级的不同阶段。像素探测器的第一次升级将包括建造一个新的像素层,该层将在LHC机器第一次关闭期间安装(LHC第一阶段升级)。新的探测器称为可插入B层(IBL),将插入现有的像素探测器和半径为3.3 cm的新(较小半径)射束管之间。IBL将需要开发几种新技术,以应对辐射或像素占用的增加,并通过减少像素尺寸和材料预算来提高物理性能。三种不同的有前途的传感器技术(平面硅,三维硅和金刚石)目前正在研究的像素检测器。本文介绍了该项目的概况,特别强调了像素模块。

英文摘要:

The upgrade for ATLAS detector will undergo different phase towards super-LHC. The first upgrade for the Pixel detector will consist of the construction of a new pixel layer which will be installed during the first shutdown of the LHC machine (LHC phase-I upgrade). The new detector, called Insertable B-Layer (IBL), will be inserted between the existing pixel detector and a new (smaller radius) beam-pipe at a radius of 3.3 cm. The IBL will require the development of several new technologies to cope with increase of radiation or pixel occupancy and also to improve the physics performance which will be achieved by reducing the pixel size and of the material budget. Three different promising sensor technologies (planar-Si, 3D-Si and diamond) are currently under investigation for the pixel detector. An overview of the project with particular emphasis on pixel module is presented in this paper.
