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

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

Caused by low Rint ( that´s the problem)

storage over christmas (3 weeks) at

Summary of bumps
• No temperature effects
• Still in specs @400V
• „Calibration“ between KA and Louvain
– Same behaviour
– Different absolute values (due to LCR-mode ?)
29.1.2003
Sensor meeting
A. Furgeri
25
Outlook
• Comparison between Cp-D mode and CpRp mode in KA
• Measurement of Louvain irrad. Mini in KA
– Comparison of Rint !
– Comparison of Rpoly increase (see Eric)
Perhaps irradiations ?
