Characterization of The Ceramic GEM for The ILCTPC — Amirrafiq Alfarra, •Serhat Atay, Ivor Fleck, and Ulrich Werthenbach — University of Siegen

The International Large Detector (ILD) will become one of the detectors of the International Linear Collider. A Time Projection Chamber, instrumented with Gas Electron Multipliers (GEM), could be constructed inside the ILD as the central tracking chamber. A new type of GEMs made out of ceramics are investigated. They have a thickness of 120 µm and a hole diameter of 200 µm. This talk will present the results from the characterization of these ceramic GEMs, especially for the properties as the gas gain and the long term stability. The results are also compared to the Garfield++ simulation. Gains of higher than 100 have been measured in an Ar:CO₂ (80:20) mixture after conditioning.
