The DIRC Upgrade for the GlueX Experiment — Ahmed Ali1,2, •Roman Dzhygadlo1, Klaus Peters1,2, Carsten Schwarz1, and Jochen Schwiening1 for the GlueX collaboration — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — 2Goethe-Universität Frankfurt
The GlueX experiment will provide the data necessary to perform quantitative tests of non-perturbative QCD by studying the spectrum of light-quark mesons and baryons. The addition of a Cherenkov-based particle identification (PID) system will significantly enhance the GlueX physics program by allowing the study of hybrid mesons decaying into kaon final states with significantly higher efficiency and purity.
The Detector of Internally Reflected Cherenkov light (DIRC) will be a compact and robust PID system utilizing optical components from the decommissioned BaBar DIRC detector. It will provide clean π/K separation for forward angles (θ<11∘) and momenta up to 4 GeV/c.
Geant4 simulation are used to optimize the design configuration of the focusing photon camera. Two reconstruction algorithms were developed to provide the best PID.
We will discuss the status of the DIRC detector and the latest achievements in the reconstruction.
