  12. DEPFET Technology (A. Andricek, Munich)

  13. DEPFET Technology (A. Andricek, Munich)

  14. DEPFET Technology (A. Andricek, Munich)

  15. DEPFET Technology (A. Andricek, Munich) ASICs: DCD and Switcher are deep submicron technologies  rad. hard beyond 10Mrad (with the appropriate design) DEPFETs: Not that easy …  … noise performance seems to be okay up to 8 Mrad threshold shift could be compensated by re-adjustment of the Switcher voltages ∆Vt variation at higher TID (reason for this under investigation) and hence ∆ID at a given VGate has to be compensated by the DCD  slightly higher noise of the f/e technological counter measures: thinner gate oxide reduces |∆Vt| further optimization of the gate dielectrics In conclusion: The DEPFET gets worse at high TIDs (8Mrad). Probably ok for several years of running

  16. DEPFET Technology (A. Andricek, Munich) Thinning technology established 50 mm + frame All silicon ~0.14% X0 (average) Collaboration forming First superBelle prototypes 2010 (PXD5) Schedule to build complete detector till 2013

  17. SOI Technology (T. Tsuboyama, KEK)

  18. SOI Technology (T. Tsuboyama, KEK) 49 Mrad! Typical problem: Back gate effect Chip submitted, still waiting Similar project by Hawaii (same submission)

  22. Data Rate & DAQ(C. Lacasta, Valencia)

  23. Data Rate & DAQ(C. Lacasta, Valencia) Gbit/s

  24. New Technologies: 3D Ron Lipton (Plenary)

  25. New Technologies: 3D Ron Lipton (Plenary) • Test run with MIT: • VIP chip: 3 layer, no sensor • Low yield, many problems • Proof of principle! Continue with Tezzaron/Ziptonix • Powerful technology Time stamp DT = 300 ns: 1/33 reduction of Occupancy!

  26. Conclusions Pixel Detector for SuperBelle should: allow robust vertexing at high background improve performance with respect to SVD2 => fast readout (or time stamp), thin Technologies: DEPFET SOI CMOS-MAPS 3D-technologie Aiming for installation in 2013 the DEPFET option seems to be the most realisitc (ok for running ~years at initial luminosity) => Tight schedule: start now! For final luminosity: consider ALL options
