The BTeV pixel detector

The pixel vertex detector is critical to the success of the BTeV experiment. It will provide very high-precision space points along charged particle trajectories with a readout fast enough so that this information can be used by the lowest level trigger. The detector will be placed in a 1.6 T dipole magnet, inside the beam vacuum, and with the innermost region as close as 6 mm from the colliding beams. The status of the technical design of this unique vertex detector is presented in this paper.
