    "abstract": "The CMS experiment at the LHC includes a hybrid silicon pixel detector for\nthe reconstruction of charged tracks and of the interaction vertices. The\nbarrel region consists of n-in-n sensors with 100X150 um^2 cell size processed\non diffusion oxygenated float zone silicon. A biasing grid is implemented and\npixel isolation is achieved with the moderated p-spray technique. An extensive\ntest program was carried out on the H2 beam line of the CERN SPS. In this paper\nwe describe the sensor layout, the beam test setup and the results obtained\nwith both irradiated and non-irradiated prototype devices. Measurements of\ncharge collection, hit detection efficiency, Lorentz angle and spatial\nresolution are presented.",
