Analysing neutron radiation damage in YBa2Cu3O7-x high-temperature superconductor tapes

Y. Linden et al.

Summary: This study investigates the lattice damage in superconducting materials caused by neutron irradiation. The research uses HRTEM analysis to quantify the degree of lattice disorder between isolated damage cascades. Results show that entropy values in both mid-frequency band FFT and DCT domains correlate with the level of lattice damage, indicating the degradation of superconducting properties. This method has implications for electron microscopy applications that require precise measurement of lattice perfection.

Recovering the performance of irradiated high-temperature superconductors for use in fusion magnets

Raphael Unterrainer et al.

Summary: Magnets in fusion devices will be affected by a significant flux of fast neutrons. Neutron radiation can lead to a decrease in superconducting transition temperature and critical current density, but thermal treatments can help recover part of the degradation. The recovery is linearly related to the annealing temperature, with higher temperatures resulting in better recovery.

Molecular dynamics simulations of radiation damage in YBa2Cu3O7

R. L. Gray et al.

Summary: The advent of high-temperature superconductors has provided the possibility of constructing smaller and cheaper fusion reactors. However, the impact of high-energy neutrons from fusion reactions on the superconductors needs to be addressed. This study uses molecular dynamics simulations to investigate the radiation-induced modifications on the crystal structure of YBa2Cu3O7, and the results show the formation of amorphous regions decorated with Cu and O defects.

Proton Irradiation Effects on the Superconducting Properties of Fe(Se,Te) Thin Films

Daniele Torsello et al.

Summary: Ion irradiation of Fe(Se,Te) films was studied to develop Fe(Se,Te) coated conductors. It was found that the films were robust against proton induced damage and an increase in critical current was achieved by introducing pointlike defects. However, damage induced in the substrate also played a crucial role in modifying film properties through variation of the strain exerted on the film.

Summary: This study numerically investigates artificially triggered magnetic flux avalanches in superconducting films by a focused laser, revealing new characteristics beyond naturally occurring avalanches. Laser irradiation can control and guide the position of flux avalanches at low ramping rates but not at high ramping rates.

In-situ measurements of the effect of radiation damage on the superconducting properties of coated conductors

W. Iliffe et al.

Summary: An apparatus was constructed for irradiation and electrical testing of REBCO coated conductors below their critical temperature. The study observed the superconducting performance of samples before and after annealing, comparing irradiation at different temperatures to understand the effect on material properties. Results showed degradation of critical temperature and critical current density with irradiation dose, but significant recovery was seen after room temperature annealing, impacting the design of high temperature superconducting magnets for fusion reactors.
