The VTX is a silicon tracker upgrade for the PHENIX experiment to provide high resolution tracking over a large coverage in both rapidity and azimuthal angle. The experimenters propose to use 120GeV protons from the Fermilab test beam to measure the efficiency, charge sharing and noise performance of the pixel ½ ladders and stripixel sensor modules. This will provide important information for the simulation and construction of the full VTX detector.
