对于sLHC第一阶段，ATLAS探测器将通过安装额外的像素探测器层进行升级。新层将插入现有像素探测器的B层和新的较小半径的束管之间。这一升级需要开发若干新技术，以科普该装置将暴露于的辐射剂量增加、粒子通量密度的显著上升以及探测器物理性能的进一步改进。实现这些目标的手段之一是显着减少的像素尺寸，使用深亚微米技术的读出芯片制造，新型材料的冷却壁建设，先进的检测器冷却方法等，在该项目的现阶段，一些关键部件正在开发的几个选项。
For the sLHC phase I, the ATLAS detector will be upgraded by installation of an additional Pixel Detector layer. The new layer will be inserted between the B-layer of the existing pixel detector and a new smaller radius beam-pipe. This upgrade requires development of several new technologies to cope with increased radiation doses to which the apparatus will be exposed, significant rise of the particle flux density and further improvement of the detector physics performance. One of the means to achieve these goals is a significant reduction of the pixel size, the use of deep sub-micron technologies for the read-out chip fabrication, novel materials for the stave construction, advanced methods for detector cooling, etc. In the present phase of the project, some key components are being developed in several options.
