The relative FWHM determined from a Gaussian fit to the experimental RSM data in (a) the qy direction, with initial FWHM values for crystals 1 to 6 of 0.08°, 0.06°, 0.15°, 0.09°, 0.11° and 0.12°, respectively, (b) the qz direction, with initial FWHM values for crystals 1 to 6 of 0.09°, 0.19°, 0.11°, 0.08°, 0.12° and 0.06°, respectively, and (c) the qx direction, with initial FWHM values for crystals 1 to 6 of 0.12°, 0.16°, 0.25°, 0.10°, 0.23° and 0.06°, respectively. (d) The relative volume expansion of the 3D RSM calculated as the total number of non-zero counts in the 3D array containing the Bragg reflection with initial RSM volumes for crystals 1 to 6 of 1838, 864, 2569, 3217, 1198 and 1005 µm3, respectively. The dose rate determined from RADDOSE-3D was 0.42 MGy s−1.
