Status of DBThe new version of PCQ acquisition program is able to write an XML file compatible with the last version of BigBrowser.

Up to now we have inserted 20 measurements into the Tracker DataBase.

Carlo Civinini, Status of PQC, Sensor Meeting, 17th Jul 2002

Status of hw + hs

HW is OK, some improvements can be done on the probe cardspresently used (cleaning or better HV insulation)

SW is OK, production version is working

Batch evaluation

HPK sets: PG01 PG02 PI42 PI43 Measurements OK, accepted beginning of July (Alu is marginal)

STM sets: PG3 PI23 PI25 PI31 PI38 PI26 PI32 KAS2 PI24 PI33 PI49HPK sets: KAH1 VI01 VI02

Most of the measurements are OK,not yet officially accepted

Carlo Civinini, Status of PQC, Sensor Meeting, 17th Jul 2002

Open points

Alu measurements are ‘marginal’ both in HPK and STM.

STM says that the metallized strip used to evaluate the aluminumresistivity is 10% narrower than the nominal (9m instead of 10mbecause of underetching).

Once verified this leads to a decrease of 10% of Alu.

VFB limits are still to be fixed according to the irradiation results.

Detector with VFB=10V seems to be OK after irradiation but we would like to see more data at higher VFB (for example 14V) before setting this limit.
