4. 29.1.2003Sensor meetingA. Furgeri 4 Impressions of opt. inspection IV&CV OK ! ?

5. 29.1.2003Sensor meetingA. Furgeri 5 Summary of optical inspection Scratches ! On surface and on backplane ! – many at the same region of the sensors (handling facility ?) – some are really deep ! Antistatic sheets to small for W5B No  -stamps on backplane No sensor failed

16. 29.1.2003Sensor meetingA. Furgeri 16 IQC Status of cyclotron: –Mechanical part ready –Electrical part problematically Old components (1962) Many improvements (automatic temperature control, flux measurement ) Comparison of Cint-ramps between Louvain and Karlsruhe Statement of main technician: „Ask in 2 weeks“

17. 29.1.2003Sensor meetingA. Furgeri 17 Cint-bumps Effect only on irradiated ST-mini´s seen Caused by low Rint (  that´s the problem) 1 mini sent to Louvain 3 mini´s sent from Louvain to us, but storage over christmas (3 weeks) at unknown temperature

18. 29.1.2003Sensor meetingA. Furgeri 18 Comparison KA-Louvain KA-mini irradiated with p Karlsruhe Louvain Same behavior! But different values !? Strip 92

19. 29.1.2003Sensor meetingA. Furgeri 19 Cint ramps 1 8 1 8 Cint Dissipation

20. 29.1.2003Sensor meetingA. Furgeri 20 Rint ramps 1 8 Maximum of Cint corresponds to Minimum of Rint

21. 29.1.2003Sensor meetingA. Furgeri 21 Ileakage ramps Profil from 400 V Udep

22. 29.1.2003Sensor meetingA. Furgeri 22 Cint ramps (2) 17 27 In middle of sensor „constant“

23. 29.1.2003Sensor meetingA. Furgeri 23 Rint ramps (2) 1 27 In middle of sensor „constant“ Lowest value ~60MOhm

24. 29.1.2003Sensor meetingA. Furgeri 24 Ileak ramps (2) Ileak ramps (2) -12°C -10°C -11°C Ileak-bumps are no effect of changing temperature during measurement

25. 29.1.2003Sensor meetingA. Furgeri 25 Summary of bumps No temperature effects Still in specs @400V „Calibration“ between KA and Louvain –Same behaviour –Different absolute values (due to LCR-mode ?)

26. 29.1.2003Sensor meetingA. Furgeri 26 Outlook Comparison between Cp-D mode and Cp- Rp mode in KA Measurement of Louvain irrad. Mini in KA –Comparison of Rint ! –Comparison of Rpoly increase (see Eric) Perhaps irradiations ?
