Test Results

• One sensor 6WA 0832 failed with high Rpoly > 2MOhm 100 strips

• All p-n junction functional @ all sensors• All capacitors within specs• Vdepl within specs• Rpoly ranges from ~1.6 MOhm to ~1.9 MOhm• One sensor showed early breakdown, was retested,

breakdown was not reproduced. Weak guard ring? All diodes were OK
