Description:
The excel file contains all data used for generating Fig.5, Fig.7, Fig.8, Fig.9, Fig.10, Fig.11, Fig.12, Fig.15, Fig.16, Fig.17, Fig.18, Fig.19 and the Zip file contains figures listed in the paper.

The figures are as follows:

Fig. 5  Average circumference change of each layer in an HCF coil calculated using the model shown in Fig. 4 (bare HCF, black dots; dual-coated HCF, red circles) subject to a temperature change from 30°C to 40°C. 
Fig. 7  Calculated dual-coated HCF relative length change when temperature is increased from 30°C to 40°C. For coiled HCF (red circles), this change is shown for the inner N layers of the 5-layer coil, Fig. 4 (b). For comparison, the change of uncoiled HCF is shown as a black solid line.
Fig. 8  Average length change in layers 1 to N (Sum of layers) for different number of turns (coil diameter: 100 mm; number of layers: 5) subject to a temperature change from 30°C to 40°C.
Fig. 9  Simulated coil performance R for different total number of layers Ntot and coil diameters of 70 mm (black squares), 100 mm (red circles), 200 mm (blue triangles), and 300 mm (green stars) subject to temperature change from 30°C to 40°C. 
Fig. 10 Simulated influence of the gap distance on coil performance R (coil diameter: 100 mm) subject to temperature change from 30°C to 40°C.
Fig. 11 Simulated influence of the HCF length on coil performance R considering coil realized experimentally (coil diameter: 160 mm; gap distance: 116 µm, turns: 57). 
Fig. 12 Simulated thermal phase sensitivity of the experimentally realized HCF coil and its comparison to the non-coiled HCF.
Fig. 15 The measured accumulated phase change of the entire HCF coil (layers 1-19) when the temperature was increased from 30°C to 40°C and from 40°C to 50°C.
Fig. 16 The measured length-normalized accumulated phase change for N = 8, 12, and 19 when subject to a temperature increase from 30°C to 40°C. 
Fig. 17 The measured length-normalized accumulated phase change for N = 8, 12, and 19 when subject to temperature increase from 40°C to 50°C
Fig. 18 The measured thermal phase sensitivity of the HCF coil with the simulated results that consider layers 16-19 to be loose.
