Electric field simulations for XENONnT — •Nikolina Sarcevic — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

The XENONnT is the next generation WIMP (Weakly-Interacting Massive Particle) dark matter detector with a 5.9 t liquid xenon (LXe) target. The electric field inside its TPC has to meet certain requirements as important parameters depend on the quality of the field: energy and position resolution, signal reconstruction, particle identification. Electric field simulations provide crucial input for the TPC design. In this talk, I will present the outcome of field simulations which led to the final design of XENONnT TPC field cage. Focus will be on the field shaping elements and how their geometrical and electrostatic characteristics shape the overall field, as well as on the influence of other TPC components.
