  2. Outline • Investigating Double ColumnProblem • in psi46digV2 • ✓test beam • ✓ x-ray • CV Measurement on DicedSensors UHH Detector Lab Meeting - 20/06/2013

  3. Test Beam Set Up UHH Detector Lab Meeting - 20/06/2013

  4. psi46dig Pixel Read Out Chip CMS Tracker Week - 15/05/2013

  5. DUT Yield vs Time psi46digV2 chip 306 > IA = 30mA > trim = 30 > 300s run > 780 Hz trigger Cluster yield vs time > drop @ 240s - clock phase jump > small step @ 100s - ? UHH Detector Lab Meeting - 20/06/2013

  6. DUT Hit Map psi46digV2 chip 306 > IA = 30mA > trim = 30 > 300s run > 780 Hz trigger Raw pixel hit map > 2 double column die during the run UHH Detector Lab Meeting - 20/06/2013

  7. DUT Yield vs Space and Time psi46digV2 chip 306 > IA = 30mA > trim = 30 > 300s run > 780 Hz trigger Rate per column vs time > 2 double column die during the run Readout errors from other columns give fake entries UHH Detector Lab Meeting - 20/06/2013

  8. DUT Yield vs Space and Time psi46 chip 205 > IA = 24 mA > trim = 30 > internal clock > 300s run > 780 Hz trigger Rate per column vs time > 6 double column die simultaneously NO readout errors with internal clock Seen in 14 over 240 runs UHH Detector Lab Meeting - 20/06/2013

  9. DUT Yield vs Space and Time psi46digV2 chip 306 > IA = 30mA > trim = 30 > external clock > 300s run > 780 Hz trigger  One hour run > 5 double column die UHH Detector Lab Meeting - 20/06/2013

  10. DUT Efficiency UHH Detector Lab Meeting - 20/06/2013

  11. Dead Double Columns psi46digV2 chip 306 > 126 runs > 33,690s > 16.7M pixel his 99 dead DC in 56 runs UHH Detector Lab Meeting - 20/06/2013

  12. Dead Double Columns psi46digV2 chip 305 > 90 runs > 31,630s > 14.5M pixel his 60 dead DC in 37 runs UHH Detector Lab Meeting - 20/06/2013

  13. x-ray Set Up UHH Detector Lab Meeting - 20/06/2013

  14. x-ray Set Up UHH Detector Lab Meeting - 20/06/2013

  15. Occupancy vs Time psi46digV2 chip 305 > IA = 30 mA > trim = 50 > 600s > NO reset NO dying DC observed UHH Detector Lab Meeting - 20/06/2013

  16. Occupancy vs Time psi46digV2 chip 305 > IA = 30 mA > trim = 50 > 600s > NO reset recovering DC observed > ? UHH Detector Lab Meeting - 20/06/2013

  17. Occupancy vs Time psi46digV2 chip 305 > IA = 30 mA > trim = 50 > 600s > NO reset ??? UHH Detector Lab Meeting - 20/06/2013

  18. Grey Room Set Up  Temperature Sensor Picoammeter Bias Source LCR Meter UHH Detector Lab Meeting - 20/06/2013

  19. Grey Room Set Up UHH Detector Lab Meeting - 20/06/2013

  20. CV Measurement After sensor dicing > depletion at ~ 80 V > step on the plateau still visible UHH Detector Lab Meeting - 20/06/2013

  21. CV Measurement After sensor dicing > depletion at ~ 80 V > step on the plateau still visible Before dicing UHH Detector Lab Meeting - 20/06/2013

  22. Summary Investigating psi46dig Double Column Issue = at test beam = with x-rays -> try to spot out some dependency CV Measurement on Sensors = drop on the plateau still observed, even after dicing CMS Tracker Week - 15/05/2013

  23. Backup UHH Detector Lab Meeting - 20/06/2013

  24. Test Beam Set Up UHH Detector Lab Meeting - 20/06/2013

  25. psi46dig Pixel Unit Cell UHH Detector Lab Meeting - 20/06/2013

  26. psi46dig Periphery UHH Detector Lab Meeting - 20/06/2013

  27. psi46dig Periphery UHH Detector Lab Meeting - 20/06/2013

  28. Double Column Readout UHH Detector Lab Meeting - 20/06/2013
