Objective
The aim of this proposal is to enhance the performance of the ATLAS detector by developing new extra endcap muon chambers (EE) which were foreseen in the original design, but which had to be de-staged because of missing resources. The new muon detectors will improve the momentum resolution of the spectrometer significantly. This detector upgrade is crucial for the search for new particle like the Higgs boson, sypersymmetric particles and additional heavy Z bosons. The EE chambers will be produced in IHEP, Protvino. The first step includes the chamber design, drift tube production, chamber glueing, assembly of gas connections and testing. In order to achieve an improved momentum resolution not only precise EE muon chambers are required but also the alignment of the chambers needs to be known with a precision better than 50 µm. This is achieved with special alignment bars, which support optical sensors. From their readings and the knowledge of the 3 dimensional positions of all sensors on the bar one can reconstruct the alignment of all muon chambers. The alignment bars will be produced and measured in Freiburg. The final chamber testing and the integration of chambers, bars and support structures will be done at CERN. An important and difficult task is the design and planning of the installation procedure of these chambers. Because they are added into the existing first phase ATLAS detector, special tooling has to be designed to fit them into the existing structures. The Weizmann group is mainly responsible for this task. The aim of this project is to produce and test 64 EE MDT chambers and 32 alignment bars and the tooling such that they are ready for installation. The installation itself will be done by the ATLAS technical coordination. The exact time of installation will depend on the schedule of shut-downs of the LHC operation.
