dc.description.abstract
High field magnets for nuclear confinement fusion reactors are a prime application for high temperature superconductors, with a multitude of privately and publicly funded concepts currently in various stages of development. However compact fusion reactors expose the superconducting magnet system to a destructive amount of fast neutron fluence, which degrade the superconducting properties. Recent simulations using an ARC-like reactor indicate that this degradation happens faster than previously expected [1], which motivates further study into the fundamental mechanisms of the degradation due to neutron irradiation damage. One of the proposed explanations has been a suppression of the superfluid density due to the introduction of pair breaking defects. Empirical observations have shown that the product of the normal state conductivity and critical temperature is proportional to the superfluid density [2]. This relation – known as Homes’ scaling – seems to hold for many conventional and unconventional superconductors. However, its validity and theoretical explanation are still under debate.
We have irradiated REBCO based thin films with neutrons in our TRIGA Mark-II research reactor, to change the charge carrier scattering rate and consequently the normal state conductivity. In contrast to irradiation experiments performed on coated conductors, the absence of any metallic layers enables us to measure the normal state transport properties in addition to the transition temperature and magnetic properties. Additionally, we assess all those different properties on the same sample, excluding sample-to-sample variation. We have observed an increase in the normal state resistivity and the Hall constant, which implies a decrease of the normal state charge carrier density. We will discuss the implications of these measurements and our measurements of the magnetic penetration depth to examine the validity of Homes’ scaling.
