EE2: Muon detector research and development for Super-LHC
Different theory scenarios predict new physics phenomena almost beyond the reach of sensititivy of LHC. If production cross sections for the creation of the new particles are very low then LHC could only discover such particles after many years of data taking. To advance the discovery potential of LHC an upgrade of the accelerator is under investigation which would yield a tenfold increased luminosity for a rather small investment. This is called Super-LHC. A tenfold increase in performance also means that all background condition get ten times worse thus posing substantial challenges to the experiments. For some particularly affected areas in the muon spectrometer of ATLAS research and development on radiation harded detector modules has been started. Currently a design with halfed diameter and length of the muon drift tubes is under scrutiny and likewise a change of the operating gas to a less sensitive mixture. These studies are pursued within a small collaboration of LMU with the Max-Planck-Institute for Physics (MPI). This research and development can also use the local accelerator infrastructure at the Maier-Leibniz-Laboratory (MLL) which was already employed in an Super-LHC investigation of muon detector modules under extrem neutron background fluxes [1].
