1 Sensor Testing Phil Turner

2 LHCb PRR - P. Turner Contents Reception Inspection Metrology Mounting Electrical tests Storage Changes since EDR Results Throughput

3 LHCb PRR - P. Turner Reception Check contents Label Create traveller Create database entry Insert data from manufacturer Store

4 LHCb PRR - P. Turner Inspection Inspect strip-side under microscope Inspect reverse Update traveller and database

5 LHCb PRR - P. Turner Metrology Weigh Height measurement Contour measurement Analyse Update traveller and database

6 LHCb PRR - P. Turner Mounting Mount sensor in carrier Label Temporary storage Bond Temporary storage

7 LHCb PRR - P. Turner Electrical tests IV Current and capacitance for each strip Re-measurements CV IV Update traveller and database Evaluation by Physicist

8 LHCb PRR - P. Turner Changes since EDR Two-person handling and inspection Two sets of jigs Simplified traveller sheet: data in database Second IV scan

9 LHCb PRR - P. Turner Storage Remove bonds Return to storage box Store in cabinet

10 LHCb PRR - P. Turner Results Total number of sensors delivered 80 35+45 Total number of used sensors 4 3+1 Total number of available sensors 48 21+27 Awaiting metrology 6 5+1 Awaiting electrical tests 9 1+8 Failed 3 1+2 Unavailable 10 4+6 Total R+P

11 LHCb PRR - P. Turner Throughput 1 sensor per 4 hour day (1h+7h+3h) 2 per 15 hour day (1h+7h+3h+1h+7h+3h) red indicates un-attended

13 Pitch Adaptor Testing Phil Turner

14 LHCb PRR - P. Turner Contents Reception Preparation Electrical tests Storage Changes since EDR Results Throughput

15 LHCb PRR - P. Turner Reception Label Create database entry Remove CERN visual failures Visually inspect Store

16 LHCb PRR - P. Turner Preparation Trim tabs Trim raised sides, if necessary Examine Temporary storage

17 LHCb PRR - P. Turner Electrical tests Probe station scan Analyse Re-measure Update database Temporary storage

18 LHCb PRR - P. Turner Storage Store sets Update database Update database when attached to hybrid

19 LHCb PRR - P. Turner Changes since EDR “Just in time” storage Record length

20 LHCb PRR - P. Turner Results Latest batch160 CERN rejects 39 Passed 70 Failed 37 Not yet measured 14 Pass rate: 65% of those tested 24 good sets tested (target: 70 good sets)

21 LHCb PRR - P. Turner Throughput 1.5 hours per pitch adaptor
