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)
