Prof. James Brau (Oregon)10/03/2006, 09:45Tracking and VertexingOralThe Yale/Oregon effort to develop a CMOS vertex detector sensor with single bunch crossing time stamping will be reviewed. The R&D program is first developing a large pixel (50 um x 50 um) sensor, with a four deep memory for each pixel, and eventually will move to fine pixels (10 um x 10um) by changing to a smaller feature size semiconductor process.Go to contribution page

Dr Nikolai Sinev (University of Oregon)11/03/2006, 11:25Tracking and VertexingOralIn our earlier investigations of radiation damage effects in a CCD based detector we observed that some parameters of the radiation damage related processes were very different from the common perception. For example, trapping time of electrons by trapping centers created by irradiation was few orders of magnitude larger than it was believed it should be. Last year we did additional...Go to contribution page

Dr Andre Sopczak (Lancaster University)11/03/2006, 12:10Tracking and VertexingOralA vertex detector concept of the Linear Collider Flavor Identification (LCFI) collaboration, which studies pixel detectors for heavy quark flavour identification, has been implemented in simulations for c-quark tagging in scalar top studies. The production and decay of scalar top quarks (stops) is particularly interesting for the development of the vertex detector as only two c-quarks and...Go to contribution page

Dr William Cooper (Fermilab)12/03/2006, 11:00Tracking and VertexingOralThe present mechanical design of the vertex detector for SiD will be described. The design includes a 12.5 cm long central barrel with silicon pixels. Four disks with silicon pixels and three additional disks, which could be based upon silicon pixels or micro-strips, are located beyond each barrel end. Since sensor technologies are rapidly evolving and final operating requirements are...Go to contribution page

Madhu Dixit (Carleton University and TRIUMF)12/03/2006, 15:35Tracking and VertexingOralThe MPGD readout TPC for the ILC will have to measure ~200 track points with a resolution close to 100 microns for all drift distances. It may be difficult to meet the resolution target with conventional MPGD readout techniques if ~2 mm wide pads were used as is presently envisioned. Reducing the pad width to improve resolution could add significantly to the detector cost and complexity....Go to contribution page
