  The Argonne Pixel Tracking Telescope is installed at the Fermilab Test Beam
Facility. The telescope consists of six planar n^{+}-in-n silicon sensors with
a pixel size of 250 {\times} 50 {\mu}m^{2}. The instrumentation of the
telescope is described including the electrical and mechanical setups. A 120
GeV proton beam is used to evaluate the telescope performance using criteria
such as the cluster size, pixel tracking efficiency, and spatial resolution.
The spatial resolution of the telescope is measured to be 72 {\mu}m {\times} 13
{\mu}m.
