The PANDA experiment of the FAIR facility will address open questions in hadron physics using antiproton beams in the momentum range of 1.5-15 GeV/c. The antiprotons are stored and cooled in the High Energy Storage Ring (HESR) and allow high precision spectroscopy in the energy range of closed and open charm. Two Cherenkov detectors using the principle of Detection of Internally Reflected Cherenkov light (DIRC) will provide excellent PID in the PANDA target spectrometer. The Endcap Disc DIRC separates pions from kaons better than 3σ up to momenta of 4 GeV/c in the forward direction, for polar angles from 5∘ to 22∘. It uses a fused silica radiator disk, consisting of four optically isolated quadrants. The Cherenkov photons are imaged on Microchannel-Plate PMTs (MCP-PMTs) by focusing lightguides. The Barrel DIRC cleanly separates pions from kaons for polar angles in the range of 22∘ - 140∘ and momenta up to 3.5 GeV/c. The barrel is formed by 16 sectors, each comprising three narrow fused silica radiator bars, with a flat mirror attached to one end and a spherical lens attached to the other, and a large fuse silica prism, coupled to each group of three lenses. The Cherenkov light is focused on the back side of the prism, where an array of lifetime-enhanced MCP-PMTs detects the photons. The designs are simulated and validated in test beams with prototypes and the Technical Design Reports of both devices have recently been completed. While mass production of some of the components has already started, the R&D for other important items, like the readout electronics or the shape and materials of the mechanical support, is still ongoing. This talk describes the status of the two DIRC projects and will discuss the remaining R&D activities.

The PANDA detector at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) in Darmstadt (Germany) will address fundamental questions of hadron physics in high-energy antiproton collisions with fixed hydrogen and nuclear targets.  The PANDA Forward RICH (FRICH) is intended for identification of charged particles with forward polar angles below 5°–10° and momenta from 3 to 15 GeV/c. PANDA FRICH will have a multilayer focusing aerogel radiator to achieve the required resolution on Cherenkov angle. A set of precisely aligned flat mirrors will collect light on the multi-anode photomultipliers which are located outside of the detector’s effective aperture. A baseline design of the PANDA Forward RICH is presented including results of the full Monte-Carlo simulation, optical measurements and prototype beam tests.

The report gives an extensive overview of the scientific and technical progress in 2018 and also summarizes the near and long term goals and the competition for the full experiment.
