| Abstract: | With increasing concern about climate change, demand for a sustainable electrical energy has skyrocketed. Green, reliable, and efficient energy sources are needed to facilitate this rising demand. To meet these requirements, a nuclear fusion power plant ITER is being built in the south of France. Besides ITER, future fusion compact reactor is a prospective energy production source, that would utilise high-temperature superconductors. These superconductors are essential to producing 20 T strong magnetic fields for achieving plasma confinement in the compact fusion reactor. Due to the high magnetic field, the superconductors would be subject to high electromechanical forces. Different Lorentz force component limitations of the state-of-the-art ReBCO tape need to be studied to prevent tape damage. One of the components is the transverse stress. Critical current against transverse stress measurements can be carried out using a transverse press in cryogenic conditions. Two press setups were explored. Bennie press was found to be improper for critical current against transverse stress measurements for the state-of-the-art ReBCO tape. A Rintje Ritsma transverse stress press setup was proposed, which was designed to improve the limitations of the Bennie press. One of the findings showed no transverse stress resistance. However, after improving the Rintje Ritsma press setup, critical current degradation did not occur until 240 MPa high transverse stress, with irreversible critical current occurring after 490 MPa. The Rintje Ritsma press setup must be further improved to validate the results. |
