Annotation	Instrumental neutron activation analysis (INAA) is a widely used method for elemental analysis. After the sample is put into a neutron field, where nuclei of interest become activated, these nuclei emit gamma photons with characteristic energies for each element. By measuring gamma spectrum of the activated sample one can determine the sample elemental composition with very high precision. In order to find out the spatial distribution of elements, the sample is usually cut into pieces, which are examined individually. Such procedure is time consuming and the spatial resolution is limited by the size of the pieces. This contribution follows up the work where the semiconductor pixel detector Timepix was used for revealing the concentration and distribution of certain elements in a whole sample at once (imaging coincidence INAA) [1]. Photons detected by a standard semiconductor detector were used to trigger the Timepix device which detected the accompanying electrons.
