Figure 5
Performance of the ENGIN-X instrument for different apertures of the incident slits located at 1.5 and 4 m from the sample position. (a) and (b) show respectively the variation of the symmetric width and intensity of the 111 peak (solid symbols) and 311 peak (open symbols) measured for a stainless-steel sample. The lines are calculations made with a Monte Carlo model of the instrument. (c) The estimated counting time, showing a minimum around 12–15 mm. (d) The divergence of the incident beam at the sample position as given by the Monte Carlo simulations.
