TM3 is able to provide the reliable measured values for the thermal fluid simulation.

The measured thermal effusivity of YBCO thin film is 1770 Jm -2s-0.5K-1. This matches with the value of bulk, 1420～2200 Jm-2s-0.5K-1.

Evaluation of super conducting thin film with thermal damagingAIST

Thermally damaged the YBCO film with high power laser and evaluated the thermal effusivity of the damaged area.

Thermally damaged the YBCO film with high power laser and evaluated the thermal effusivity of the damaged area. The thermal effusivity of the area is 2% lower than non damaged areas. S. Ikeuchi et al. J. Cryo. Soc. Jpn 40 335 (2005)
