Abstract
A microstrip gallium arsenide detector (thickness 508 mu m, strip widt h 100 mu m, strip pitch and readout pitch 200 mu m) has been tested in a 50 GeV/c electron beam at CERN. Using the low noise Viking preampli fier chip (shaping time similar to 1.5 mu s) signal to noise ratios up to 25 were measured depending on bias voltage and angle of incidence. Applying the so-called eta-algorithm (using the impact position-sensi tive charge sharing between adjacent strips) a resolution down to sigm a similar to 20 mu m could be obtained.
