1 EU midterm review, 8 th Dec Carsten Schwarz PANDA

2 EU midterm review, 8 th Dec 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.

3 EU midterm review, 8 th Dec Carsten Schwarz for long bars and internal reflection temperature controlled (dT < 0.1 o C) 35mm 14mm GSI test box for light attenuation

4 EU midterm review, 8 th Dec Carsten Schwarz Uni Mainz TOF tests Measure exit angle to improve timing resolution S. Sanchez, Uni Mainz

5 EU midterm review, 8 th Dec Carsten Schwarz Radiator Test Stand Glasgow CARY 300 spectrophotometer sensitivity of Abs between 200nm and 800nm in 1nm steps systematic studies using materials to be tested show accuracy of < 0.2% Fused Silica with/without GlueMatsushita Aerogel n=1.03 Reference beam Sample beam

6 EU midterm review, 8 th Dec Carsten Schwarz Timelines + milestones Barrel DIRC

7 EU midterm review, 8 th Dec Carsten Schwarz Forward Cerenkov Forward Cerenkov detektor

8 EU midterm review, 8 th Dec 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
