The Barrel DIRC of the PANDA experiment at FAIR will cleanly
separate pions from kaons for the physics program of PANDA. Innovative solutions
for key components of the detector sitting in the strong magnetic eld of the compact
PANDA target spectrometer as well as two reconstruction methods were developed
in an extensive prototype program. The technical design and present results from
the test beam campaigns at the CERN PS in 2017 and 2018 are discussed.
