We report on test beam measurements of GaAs detectors. The detectors d
iffer in pitch (44, 200, 375 and 1000 mu m) and thickness (d = 500 and
200 mu m). Results on the charge collection, the signal to noise rati
o and the charge division were obtained with a 5 GeV/c pion beam at th
e CERN-PS. Position dependent measurements of cross-talk between strip
s and the charge collection efficiency (CCE) were performed at the 1.5
MeV He+ beam of the Freiburg Van de Graaff facility.
