Tasks and time scale

• T. Tsuboyama (KEK)

2
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

3
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

4
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

5
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

6
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.

7
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 (CDCSVDPIXEL)
  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)
