1 EU midterm review, 8 th Dec. 2006 Carsten Schwarz PANDA

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.

3 EU midterm review, 8 th Dec. 2006 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. 2006 Carsten Schwarz Uni Mainz TOF tests Measure exit angle to improve timing resolution S. Sanchez, Uni Mainz

5 EU midterm review, 8 th Dec. 2006 Carsten Schwarz Radiator Test Stand Glasgow CARY 300 spectrophotometer sensitivity of 0.001 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. 2006 Carsten Schwarz Timelines + milestones Barrel DIRC

7 EU midterm review, 8 th Dec. 2006 Carsten Schwarz Forward Cerenkov Forward Cerenkov detektor

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
