    Abstract

    This note describes the systematic study made of the resolution of the LHCb VELO telescope used in the Autumn 99 test-beam. Measurements were made of the resolution for each region of both the LHCb {\it R} and Φ vertex detectors. The best value obtained for a 40μm pitch detector was 5.8 ± 0.5 μm, which is comparable to the 6.0 μm prediction of the Technical Proposal. At larger pitches, it was found that the resolutions deviate from those given in the Technical Proposal e.g. for an 80 μm detector a resolution of \mbox{15.4 ± 0.3 μm} is compared to the Technical Proposal value of 10 μm.
