Development and characterization of a new time reference plane and trigger system for a MIMOSA26 test beam telescope — •Rasmus Partzsch, Christian Bespin, Yannick Dieter, Fabian Hügging, Lars Schall, and Jochen Dingfelder — Physikalisches Institut, University Bonn, Germany

Test beam telescopes facilitate a characterization of different detector parameters and consist of multiple detector planes with high spatial resolution. ANEMONE is a beam telescope, comprising 6 MIMOSA26 planes. Because of the MIMOSA26 readout cycle, multiple hits are included in a single readout frame. To resolve individual tracks within the readout cycle, a reference detector with high precision time-stamping capabilities is required. Currently, the ATLAS FE-I4 chip is utilized as such. For the ATLAS inner tracker upgrade, the ITkPix readout chip was developed, featuring a smaller pixel size and the same time resolution as the FE-I4. A replacement with the new ITkPix chip enables a more efficient track reconstruction. Additionally, it can be utilized to provide a region-of-interest trigger in conjunction with the new AIDA TLU. It provides clock and time-stamp synchronization with the DUT and a more complex triggering logic compared to the previously used EUDET TLU. A new Python-based control software for the AIDA TLU has been developed for usage with the ANEMONE beam telescope.

In this talk, the integration of the AIDA TLU into the ANEMONE telescope is demonstrated. In addition, results with the upgraded time reference plane in terms of track reconstruction efficiency are shown.
