Sumario:Multi-geometry silicon prototype sensors designed for the LHCb Inner Tracker have been studied in a test beam performed in the X7 beam line at CERN in May 2002. Measurements were made using the Beetle 1.1 analogue front-end chip and a sampling at 40 MHz. In this note results on resolution, signal-to-noise, noise rates and efficiencies are presented as function of the bias voltage and for different shaping times. Based on these results a decision will be made on which geometry will be implemented in the final sensors for the LHCb Inner Tracker.
