+In order to prove the concept of a DIRC detector made of acrylic glass
+and to test and debug the electronics envisaged for the PANDA DIRC
+detectors under experimental conditions, a prototype setup was placed
+in J\"{u}lich behind the TOF experiment (\cref{fig:juelich}) in
+October 2012. Here, protons with a momentum of $2.95$\,GeV and a rate
+of $10^7$\,Hz were scattered at a target and detected in two different
+DIRC detectors. Additionally, different multi-anode PMTs were tested.
+The PaDiWa single photon detection efficiencies for MaPMTs and MCPs
+equal to those of standard NIM based discriminators and amplifiers
+used in previous tests. In total, $10$ TRB3s with PaDiWa front-ends
+were used providing $2400$ channels, which was the largest system of
+TRB3s used in a test beamtime so far. This test experiment showed the
+need of an easy-to-handle and economical DAQ platform such as the
+TRB3.
