Description
The PANDA experiment at the future FAIR facility will use antiproton annihilations to investigate open questions in hadron physics in
the momentum range of 1.5-15 GeV/c. A Barrel DIRC detector will be
built for the PANDA target spectrometer in order to achieve excellent charged particle identification (PID), which is needed to cleanly
separate π/K/p.
Based on the successful BaBar DIRC detector with added key improvements, this detector will perform a better-than 3σ π/k separation in the momentum range of 0.5 GeV/c to 3.5 GeV/c and in the polar angle range of 22° to 140°.
The Barrel DIRC counter will use enhanced-lifetime MCP-PMTs for photon detection in combination with fast readout electronics.
The radiators are made from highly polished synthetic fused silica to ensure that photons, propagating through the radiators by total internal reflection, conserve the Cherenkov angle and
reach the photon detection plane without angular distortions.
The DIRC principle, key components and the expected PID performance will be presented in this talk.
