A beam telescope providing precision track measurements as reference for ot
her detectors has been upgraded in the CERN H2 test beam. The apparatus was
completely rebuilt from the detector wafers and front-end electronics to t
he data acquisition system. The new detector setup consists of eight 5.6 x
5.6 cm(2) sized DC coupled silicon microstrip detectors. Typical position r
esolution values of about 7.5 mu m were measured. Details of the setup are
described and results from the recent beam tests are reported. (C) 1999 Els
