Query: Installation and Commissioning of the GlueX DIRC   The GlueX experiment takes place in experimental Hall D at Jefferson Lab
(JLab). With a linearly polarized photon beam of up to 12 GeV energy, GlueX is
a dedicated experiment to search for hybrid mesons via photoproduction
reactions. The low-intensity (Phase I) of GlueX was recently completed; the
high-intensity (Phase II) started in 2020 including an upgraded particle
identification system, known as the DIRC (Detection of Internally Reflected
Cherenkov light), utilizing components from the decommissioned BaBar
experiment. The identification and separation of the kaon final states will
significantly enhance the GlueX physics program, by adding the capability of
accessing the strange quark flavor content of conventional (and potentially
hybrid) mesons. In these proceedings, we report that the installation and
commissioning of the DIRC detector has been successfully completed.
