2. EU midterm review, 8 th Dec. 2006 Carsten Schwarz PANDA 1 Cerenkov Imaging Detectors Design and prototyping of RICH subdetectors for the PANDA experiment. Barrel DIRC  R&D on quality of radiator slabs (fused quartz)  R&D on simplification of readout by using timing information (Time of propagation) and 1- dimensional spatial information Endcap RICH  R&D on using the DIRC principle.

8. EU midterm review, 8 th Dec. 2006 Carsten Schwarz Radiator quality measurements are in good progress (GSI) Photon detection measurements towards a small photon detector with APD-array is running (SMI) Improvements of TOF-measurements are studied (Uni Mainz) Design studies of Endcap-RICH point towards DIRC principle. (Glasgow/Edinburgh) Radiator and photon detector test stands fully operational by end of the year (Glasgow) Deliveries (TDR) expected to be made on schedule
