Abstract
A 2D neutron detector based on 3He convertor and MWPC with an active area of 200 mm \times 200 mm has been successfully designed and fabricated. The detector has been tested with Am/Be neutron source and with collimated neutron beam with wavelength of {\lambda} = 1.37 {\AA}. A best spatial resolution of 1.18 mm (FWHM) and good linearity were obtained. This is in good agreement with the theoretical calculations.
