Tasks and time scale T. Tsuboyama (KEK)

DSSD production Test production by Micron and SINTEF (Talk by M. Valentan) HPK decided to restart DSSD business. – The first sample comes in 1.5 years Mass production – Sensor characterization. – Quality control

Readout APV25 hybrid – Origami (C. Irmler) and Normal – Production – Quality control --- Test Repeater – Location should be decided. (Not yet clear) – Mechanical and Electric design – Mass production Backend – COPPER/FINNESSE – Mass production DAQ software – Slow control

Mechanics Discussion with KEK engineering group has started. Support – Joint work with IR/DEPFET/Strip design is necessary – Connection to CDC/IR/DEPFET – Design: Cooling of normal hybrids – Construction Ladder production – Design – Assembly procedure – Storage – Booking and testing Ladder mount scheme and procedure

Infrastructures Monitor – Radiation and Beam abort – Temperature Cooling – Chiller/coolant – tubing – Special consideration of Origami cooling tubes Cables – Power supply / signal / control / Power supply: – 3 times larger system than the present SVD Krakow and Prague groups are designing power supply system common to SVD and DEPFET

System integration Definition of Integration strategy. Online software – Cluster finding and time reconstruction – Calibration – Performance monitor Data quality monitor Quality assurance monitor Test with source /laser (?) Debugging hardware and software Calibration Cosmic ray test Commissioning Pixel + SVD should be done together.

Offline Software Hara san is now working for overall computing and has not time to contribute to SVD Calibration / Database Alignment – For physics study, much better svd/pixel alignment and reliable tracking (CDC+SVD+PIXEL) is necessary Simulations – A GEAN4 version is reported by Drasal (Prague) – Detector optimization Tracking – CDC track extrapolation – Evaluation of SVD only tracking A. Moll (MPI) – New alignment efforts A. Moll (MPI)
