Track reconstruction at the TPC of the ILD with pixelated readout — •Martin Rogowski, Klaus Desch, and Jochen Kaminski — Physikalisches Institut, Universität Bonn, Nußallee 12, 53115 Bonn

The International Large Detector is intended to utilize a Time Projection Chamber (TPC) as a tracking device. This TPC is envisaged to have a high momentum resolution of about σ1/pT≈ 2×10−5GeV−1. This resolution can be achieved through the use of fine granulated detectors.

One choice of fine granulated detectors are the so called InGrids. These are pixel chips on which a structure similar to Micromegas is fabricated with postprocessing techniques. This allows the holes of the grid of the Micromegas to be aligned with the pixels.

To exploit this higher resolution and the huge number of space points, tailored track reconstruction algorithms have to be implemented. In the talk some algorithms are presented and will be compared.
