High Temperature Thermocouple Use in Strong Magnetic Fields*

Thermomagnetic processing of materials at high temperatures and in high magnetic fields requires an understanding of in situ temperatures experienced by the samples/workpieces. Here, the performance of Type-K thermocouples is compared to Type-N and Type-S alternatives in two different thermomagnetic processing configurations, one with rf induction coils and the other with resistance heating elements. The results will be reported for studies spanning magnetic fields up to 9 T and temperatures up to 1000 C.
