-This most recent test beamtime took place in July 2013 at the MAMI-B
-microtron in Mainz (electron accelarator) with an beam energy of
-$855$\,MeV for the development of the Barrel DIRC detector at PANDA
-(\cref{fig:mainz}). In total, 4 TRB3s with TDC implementations were
-used with two different discriminator front-ends: The PaDiWa and the
-NINO ASIC. It turned out that the difficult threshold setting for the
-PaDiWa lead to worse results compared to the NINO ASIC. However, the
-TRB3 provided a stable platform for a successful test beamtime.
+This most recent test experiment, for the development of a Barrel DIRC
+detector for PANDA (\cref{fig:mainz}), took place in July 2013 at the
+MAMI-B microtron in Mainz (electron accelerator) with a beam energy of
+$855$\,MeV. A Cherenkov counter prototype using the DIRC principle was
+placed in the beam line. The prototype comprises a highly-polished
+fused silica bar with a lens attached, an oil-filled expansion volume
+and a photon detector matrix of up to $6$ $64$-channel MCP-PMTs which
+were read out by the TRB3 system. In total, 4 TRB3s with TDC
+implementations were used with two different discriminator front-ends:
+the PaDiWa and the NINO ASIC. The beam current was set to achieve a
+trigger rate of approximately $6$\,kHz. The results show a worse
+Cherenkov photon detection for PaDiWa with respect to the NINO ASIC,
+as seen in the hit patterns, which is probably caused by differences
+in the amplification stage (the gain of the latter is $100$ times
+larger). However, the TRB3 provided a stable platform for a successful
+test beamtime.
