Transverse Diffusion in the TPC of the T2K Near Detector — Philp Hamacher-Baumann, Lukas Koch, •Thomas Radermacher, Stefan Roth, and Jochen Steinmann — III. Physikalisches Institut B, RWTH Aachen University, D-52056 Aachen

Transverse diffusion affects the spatial resolution in a Time Projection Chamber (TPC). In the TPCs of the T2K near detector it can be derived from the charge distribution on the Micromegas plane. The electron cloud width is reconstructed from the charge fraction detected by the individual anode pads. This cloud width is investigated in dependence of the drift distance and the transverse diffusion coefficient is extracted.
