  A semiconductor tracker for muon scattering tomography is presented. The
tracker contains silicon strip sensors with an $80\,\mu$m pitch, precision
mechanics and integrated cooling. The electronic readout of the sensors is
performed by a scalable, inexpensive, flexible, FPGA-based system, which is
demonstrated to achieve an event rate of $30\,$kHz. The tracker performance is
compared with a Geant4 simulation. A scattering angle resolution compatible
with $1.5\,$mrad at the $4\,$GeV average cosmic ray muon energy is
demonstrated. Images of plastic, iron and lead samples are obtained using an
Angle Statistics Reconstruction algorithm. The images demonstrate good contrast
between low and high atomic number materials.
