11. 6/22/2015Tracker Week April 2002IEKP 11 Strip parameter ST teststructure calibration KA-Louvain Interstrip capacitance: KA 0.64pF (1 neighbour) Louvain 1.05pF (2 neighbours)

12. 6/22/2015Tracker Week April 2002IEKP 12 Future calibration Second calibration run Calibration with an irradiated teststructure Anealing curve each 20 min @ 50°C, agreed with Louvain. IV & CV taken.

13. 6/22/2015Tracker Week April 2002IEKP 13 FINAL SET All measurements after 80 min @ 60°C and > 6h in the fridge All measurements @-10°C DIODE: –IV, CV (100kHz with guard on GND; (test also 1MHz))  I_TOT, V_dep, C_TOT,  Minisensor or full sensor  IV, CV (1kHz)  Strip measurements: all on 2 DC pads Rpoly, Cint, Rint, leakage current –Before irrad, full stripscan @ 400V –After irrad: 10 strips (later ~5) voltage (IQC) ramp 10V/s [10-500V]  For the beginning: full check for pinholes (Idiel@10V; CC (100Hz) without ramps all @ Vbias= 20V) All Cap measure with parallel mode!

14. 6/22/2015Tracker Week April 2002IEKP 14 Preliminary Irrad tables already exist in XML Tables are done and already underwent one iteration between Karlsruhe and Louvain; discussion with Didier done! The IQC tables will belong to the sensor ID=same object!! We will have 2 new composites with 3 simple tables: –1. composite: diode minisensor –2. composite: sensor –Tables show the results from: [ R poly ;C int ;I leak ;R int (CAC optional)]@V standard =400V ONE Ramp, values @Vbias=400V Delta of values before and after irradiation ( Environment
