Our group operates the Silicon Beam Telescope (SiBT) at the CERN H2 test beam area. The telescope is used for measuring tracks of incoming particle beams with high resolution i.e. it provides a reference measurement for studying new detectors.

The telescope was rebuilt in 2007 using CMS DAQ components from the Tracker module testing and Fermilab D0 RunIIb silicon strip sensors. The interpolated position resolution of the SiBT telescope is 9 µm, it has a S/N of 25 and an active area of 4 x 4 cm2. The telescope contains 8 reference detector planes in ±45 degree orientation and has two slots in the middle of the telescope for the devices to be tested. The telescope can be cooled down to -20°C temperature, which is very beneficial when studying highly irradiated sensors.
