The ATLAS Tile Calorimeter Trigger and Data Acquisition Interface — •Thomas Junkermann and Tigran Mkrtchyan — Kirchhoff-Institut für Physik Heidelberg

The Phase-II Upgrade of the ATLAS Tile Calorimeter (TileCal) is a replacement of the entire on- and off-detector electronics to cope with the higher amount of simultaneous proton-proton collisions of future LHC runs. New back-end electronics are designed to provide high-bandwidth data to the new Phase-II Trigger and Data Acquisition (TDAQ) system. The Tile Calorimeter Trigger and Data Acquisition Interface (TDAQi) is an ATCA rear transition module and as part of the new TileCal PreProcessor serves as the connection between the off-detector calorimeter electronics and the TDAQ system of ATLAS. After the calorimeter cell signals are received and energies reconstructed by the Compact Processor Modules, the TDAQi prepares the data for further use. Cell energies are converted to transverse energy, cells are sorted or added to larger sums for the trigger and various threshold comparisons for muon candidate identification are provided. Additionally, the TDAQi forwards these intermediate results to the DAQ system for monitoring. The TDAQi as part of the ATLAS Phase-II upgrade will be presented. Together with latest hardware validation and integration tests, the general TDAQi status is featured.
