摘要
A two dimensional position-sensitive neutron detector has been developed at the Geesthacht Neutron Facility (GeNF) for the new diffractometer ARES which is dedicated to the analysis of residual stresses. The detector is a He-3 and CF4 filled multiwire proportional counter with delay line readout and has a sensitive area of 300 mm x 300 mm. The detector was tested at different He-3 and CF4 partial pressures with a well collimated neutron beam. Excellent linearity and homogeneity of the detection probability combined with a spatial resolution of about 2 mm x 2 mm. were found. (C) 2002 Published by Elsevier Science B.V.
