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 consequence, the uncertainty in the hadronic light-by-light (HLbL) calculation for the anomalous magnetic moment of the muon can be reduced. The detector system for the experiment is a modified version of the PANDA backward calorimeter, which was developed by the group at HI-Mainz. In contrast to the PANDA experiment, the detector will operate in forward direction at a fixed target electron scattering experiment. Thus, new challenges arise for the radiation load of the components and the handling of high rates with the data acquisition. The talk addresses the major hardware, electronics, and data acquisition modifications to the PANDA backward calorimeter to achieve Phase-0 readiness.
