Figure 4 The time needed to attain 10-4 strain accuracy in reflection geometry based on representative neutron calibration data (acquired at Chalk River) for a 40  mm3 Ni gauge volume, with no background, or a background level equal to that recorded near the surface, compared with the decreasing background response predicted from the calibration data (Fig. 2). The 60  min maximum feasible time threshold is marked by the dashed line.
