Table 3: Comparison of neutron diffraction and XRD results of Nb3Sn and Cu lattice parameters in radial and hoop directions in the four largest conductor blocks in the 11 T coil centre. Nb3Sn lattice parameters are calculated from the d-spacing of the (321) reflection. The Cu lattice parameter is calculated from the d-spacing of the (200) reflection (XRD) or the (220) reflection (neutron diffraction). The sample volume probed by XRD is 5×5×3 mm3, and the neutron diffraction nominal gauge volume is 5×5×5 mm3.
