The Data Acquisition for PANDA FAIR Phase-0 at MAMI — Luigi Capozza¹, Jonas Geisbüsch¹, Ravi Gowdru Manjunata¹, Samet Katilmis¹, Frank Maas^1,2,3, •Oliver Noll^1,2, David Rodriguez Piñeiro¹, Paul Schöner¹, Christoph Rosner¹, and Sahra Wolff¹ for the PANDA collaboration — ¹Helmholtz-Institut Mainz, Mainz, Germany — ²Institute of Nuclear Physics, Mainz, Germany — ³PRISMA Cluster of Excellence, Mainz, Germany

The PANDA FAIR Phase-0 experiment at the Mainz Microtron Facility (MAMI) is set to determine the double-virtual transition formfactor (TFF) of the pion. As a result, the uncertainty in the hadronic light-by-light (HLbL) calculation can be reduced. Consequently, the experiment will give new input to the hadronic corrections of the anomalous magnetic moment of the muon (g_µ-2 puzzle). The detector system for the experiment is a modified version of the PANDA backward calorimeter, which was designed by the electromagnetic process group (EMP) at HI-Mainz. In contrast to the PANDA experiment, the detector will operate in forward direction within a strong electromagnetic environment. The PANDA FAIR Phase-0 data acquisition is optimised to record the exclusive signal channel under high-background conditions. The talk addresses the readout chain with the analogue frontend, the digitisation using the PANDA SADC, the digital signal processing on FPGAs and the efficient data transmission via the Trigger Bus Synchronisation System (TRB).
