Development of a computer-assisted instrumentation platform for high-Tc superconductor phase transition measurement with LabVIEW and ELVIS II

Abstract

The article proposes the development of a computer-assisted instrumentation platform for high-Tc superconductor phase transition measurement with LabVIEW and ELVIS II for the undergraduate laboratory. We demonstrate the strategies to establish the knowledge and the skills to overcome the challenges in precise measurements, including (a) the construction of human-computer interfaces of the circuit system; (b) synchronized acquisition and analysis of big and fast variation data; (c) a real-time demonstration of resistance-temperature dynamics; and (d) problem shooting and solution proposing from physics and engineering perspectives. The work also demonstrates that the strategies to complete the measurements with self-designed simple circuits and available alternatives and intelligent-service program effectively turn passive reliance into creativity and stimulates technical practice with imagination.
