COSM's ATLAS tracker upgrade project

ATLAS Upgrade for sLHC

It is expected that the ATLAS detector will be upgraded after about eight years of operation, to work with an upgraded (or super) LHC. That is about ten years from now. Experience has shown that the time to prepare a new detector is about ten years or longer, including R&D, testing, any technology selection process, fabrication, and assembly.

The technology used for the TRT (drift tube detectors) will not handle the particle flux from the sLHC, due its proposed high luminosity (of 10^35 /cm^2/s). Therefore the Hampton group is exploring, in conjunction with BNL and LBL, using silicon detectors to replace the tracking currently done by the TRT.

As a first practical step, we have obtained from LBL parts for an ATLAS Semiconductor Tracker (SCT) module test station, and are in the process of setting up such a station.

We will investigate cooling methods with this station, and have purchased a chiller capable of going to -30 deg.C.
