Description

The PANDA detector at the international accelerator Facility for Antiproton and Ion
Research in Europe (FAIR) near GSI, Darmstadt, Germany will address fundamental questions
of hadron physics.

Excellent Particle Identification (PID) over a large range of solid angles and
particle momenta will be essential to meet the objectives of the rich physics program,
which includes charmonium spectroscopy, the search for hybrids and glueballs, and the
study of the interaction of hidden and open charm particles with nucleons and nuclei.
Charged PID for the barrel section of the target spectrometer will be provided by
a DIRC (Detection of Internally Reflected Cherenkov light) detector.
This counter will cover the angular range of 22-140 degrees and will need to cleanly
separate charged pions from kaons for momenta between 0.5 GeV/c and 3.5 GeV/c with a
separation power of at least 3 standard deviations.

The design of the PANDA Barrel DIRC detector is based on the successful BABAR
DIRC and the SuperB FDIRC R&D with several important improvements to optimize the
performance for PANDA, such as a focusing lens system, fast timing, and a compact fused
silica prism as expansion region.

We will discuss the baseline design of the PANDA Barrel DIRC, based on narrow bars
made of synthetic fused silica and a complex multi-layer spherical lens system,
and the potentially cost-saving design option using wide fused silica plates and
will present the result of tests of a large system prototype with a mixed
hadron beam at CERN.
