P. Vázquez R&D in microstrip silicon detectors nIn case the pixel option cannot meet the physics and time scale requirements, the silicon strip option should hold for LHCb VELO upgrade nThe strip option should stay as close as possible to the current design improving its performance n 40 MHz readout n Higher granularity (x10 luminosity increase) n Impact Parameter resolution n Radiation hardness nUSC wants to participate in the design and characterization of the new sensors, in the module assembly and tests with particle beams at CERN nVery useful for the FTD conception of ILC IV jornadas FLC, Madrid, 2-3 Dec
