We are running a new series of weekly online seminars on Applied Superconductivity to give researchers in the field an opportunity to present their work and to strengthen networks in the community. The events are particularly aimed at giving early career researchers a forum for presenting their work, but we also welcome industry speakers and more experienced guest speakers.

CfAS scientist Martina Esposito, working in the Leek group, developed a Josephson parametric amplifier (JPA) based on a lumped-element LC resonator which includes an array of superconducting quantum interference devices (SQUIDs). The main figures of merit of the device are a bandwidth BW = 15 MHz, a maximum gain G = 21 dB and a 1-dB compression point of -115 dBm. The characterization of the gain of the amplifier is shown in the figure.

Researchers from Oxford’s Centre for Applied Superconductivity (CfAS) in Oxford Physics have uncovered the impressive properties of a novel superconductor, marking it out as the best of its kind with huge technological potential. The novel material in question, CaKFe4As4, was first synthesised only a couple of years ago both in Japan and Ames Laboratory, USA. Remarkably, its critical current density in single crystals was found to exceed that of all known iron-based superconductors, with a value of around 107 A/cm2.
