abstract = {Next-generation DIRC detectors, like the PANDA Barrel DIRC,
with improved optical designs and better spatial and timing
resolution, require correspondingly advanced reconstruction
and PID methods. The investigation of the PID performance of
two DIRC counters and the evaluation of the reconstruction
and PID algorithms form the core of this thesis. Several
reconstruction and PID approaches were developed, optimized,
and tested using hadronic beam particles, experimental
physics events, and Geant simulations. The near-final design
of the PANDA Barrel DIRC was evaluated with a prototype in
the T9 beamline at CERN in 2018. The analysis finds
excellent agreement between the experimental data and the
Geant simulations for all reconstruction algorithms. The
best PID performance of up to $5.2 \pm 0.2$ s.d. $\pi$/K
separation at 3.5 GeV/c, was obtained with a time imaging
PID method. The PANDA Barrel DIRC simulation, as well as the
reconstruction and PID algorithms, were evaluated using
experimental data from the GlueX DIRC as part of the FAIR
Phase-0 program. The performance validation was carried out
using physics events of the GlueX experiment and
simulations. The initial analysis results of the
commissioning dataset show a $\pi$/K separation power of up
to 3 s.d. at a momentum of 3.0-3.5 GeV/c, obtained using a
geometric reconstruction algorithm.},
