Summary of optical inspectionSummary 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

IQCIQC

• 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“


Cint-bumpsCint-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

Ileak-bumpsare no effectof changing temperatureduring measurement


Summary of bumpsSummary of bumps

• No temperature effects

• Still in specs @400V

• „Calibration“ between KA and Louvain– Same behaviour– Different absolute values (due to LCR-mode ?)


OutlookOutlook

• 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 ?
