Abstract
The proposed luminosity upgrade to the LHC imposes significant challenges on the LHC detectors: their design must function within a much harder radiation environment and yet preserve, if not improve, their ability to maximize the upgrade's physics opportunities. In addition, they must be designed, constructed, and installed on a tight timescale in order to be ready for operation in 2016. For ATLAS, the upgrade entails a major redesign of the tracking systems, and possibly the forward calorimeters and muon detectors as well. Efforts have already begun to address these issues.

The ATLAS muon spectrometer was designed with a safety factor of 5 over the expected cavern background rate; if the SLHC background rate is roughly 10 times this expectation, most of the muon detector occupancies will remain below 30%, except in the inner and middle endcap layers
Summary
The ATLAS detector is a multi-purpose particle detector optimized for high-pT physics at the LHC. In a 2 T solenoidal magnetic field, is the Inner Detector (ID), consisting of silicon pixels and strips as well as a Transition Radiation Tracker (TRT). These systems provide charged particle tracking in the pseudorapidity range |η| < 2.5. A discussion of upgrade machine (SLHC) scenarios can be found elsewhere in these proceedings [2], as well as a summary of its physics potential [3]. This article summarizes some of the issues and studies underway to address the challenges of pursuing physics at the SLHC with the ATLAS detector. As the machine upgrade has become better understood, upgrade plans have become more focused, with more detailed studies beginning
