Building and testing a TPC for IAXO and developing reconstruction algorithms — Ivor Fleck, •Jan Joachim Hahn, and Ulrich Werthenbach — Universität Siegen

We present the detection and reconstruction of X-rays in a time projection chamber. A test chamber has been especially designed and build for this purpose for the upcoming Baby IAXO and IAXO experiment. The chamber operates with an Ar:CO₂ mixture at a ratio of 80:20. The readout is done using an InGrid chip. A first reconstruction algorithm has been developed to reconstruct the events and distinguish between photons and background. The used algorithm is a based on the Cambridge-Aachen algorithm with additional discriminators to further supress the background events. The tests are done using ⁵⁵Fe X-rays as a test signal.
