A novel self-supporting GEM-based amplification structure for a time projection chamber at the ILC
Description
In this paper, a new self-supporting way to mount Gas Electron Multipliers is presented. It has been developed to provide a method to cover large readout areas while ensuring the flatness of the foils and keeping the amount of dead material minimal. The structure has been tested in a Time Projection Chamber prototype, using cosmic muon tracks. The impact of the mounting structure on the track reconstruction and the single point resolution is quantified and its impact on the tracking efficiency and dE/dx measurements is estimated.
