The detection of neutrons with high spatial resolution by a pixelated silicon semiconductor silicon detector requires the use of a thin converter. A 6Li based converter was used for this purpose in our work. We demonstrate that unwanted gamma rays and electrons accompanying neutron beam can be effectively suppressed using pattern recognition of the analyzed particle tracks, where spectroscopic ability of the detector was advantageously used. Neutron detection with micrometric spatial resolution is reached by appropriate fitting of identified heavy charged particles by the Gaussian distribution.
