Uncertainty analysis of axial temperature and Seebeck coefficient measurements

Seebeck coefficient measurements of lithium isotopes

Lithium, owing to its many advantages, is of immense interest to the fusion community for its use as plasma facing component (PFC) material. Various experiments are under progress in the Center for Plasma Material Interactions (CPMI) at the University of Illinois at Urbana Champaign (UIUC) aimed at understanding the plasma–lithium interactions. In one such experiment called Solid/Liquid Lithium...

Apparatus for Seebeck coefficient and electrical resistivity measurements of bulk thermoelectric materials at high temperature

A high temperature Seebeck coefficient and electrical resistivity measurement apparatus has been designed and built for measuring advanced thermoelectric materials. The apparatus covers the range of temperatures from 300 to 1300 K. Different sources of errors involved in the two measurements are discussed. The accuracy of the electrical resistivity measurement is estimated to be better than ±1%...

Seebeck coefficient measurements on Li, Sn, Ta, Mo, and W

The thermopower of W, Mo, Ta, Li and Sn has been measured relative to stainless steel, and the Seebeck coefficient of each of these materials has then been calculated. These are materials that are currently relevant to fusion research and form the backbone for different possibl e liquid limiter concepts includ ing TEMHD concepts such as LiMIT. For molybdenum the Seebeck coefficient has a linear...

A high temperature apparatus for measurement of the Seebeck coefficient.

A high temperature Seebeck coefficient measurement apparatus with various features to minimize typical sources of error is designed and built. Common sources of temperature and voltage measurement error are described and principles to overcome these are proposed. With these guiding principles, a high temperature Seebeck measurement apparatus with a uniaxial 4-point contact geometry is designed ...
