Characterization of Ceramic GEM for The International Large Detector — •Serhat Atay, Ulrich Wertenbach, and Ivor Fleck — University of Siegen

The International Large Detector (ILD) will become one of the detectors of The International Linear Collider (ILC). A Time Projection Chamber (TPC), instrumented with Gas Electron Multipliers (GEM), will be constructed inside the ILD as the central tracking chamber. Different GEM prototypes are proposed. This talk will present result from characterization of ceramic GEMs, especially for gas gain and long term stability. They have been produced with a thickness of 120 um and a hole diameter 200 um. Gains of up to 100 have been measured in an Ar:CO2 mixture.
