ATLAS BEAM TEST-RESULTS

Many different configurations of electronics and-semiconductor strip d etectors were studied in 1995 using the ATLAS tracking detector test a rea at the H8 beam-line of the CERN SPS. A significant fraction of the se investigations are presented elsewhere in this volume and this pape r will concentrate on the results with silicon strip detectors read ou t with electronics preserving the pulse height information. Data has b een collected with the ADAM, APV5 and FElix read-out chips on a number of different detectors. The first results are presented for read out with LHC electronics of detectors to the ATLAS-A specification of 112. 5 mu m pitch, employing n-strips in n-type silicon, capacitive couplin g and intermediate strips. It is demonstrated that with adequate signa l/noise, a spatial resolution of similar or equal to 13 mu m is attain able with these detectors.
