Fabrum Solutions and Callaghan Innovation have been developing large pulse tube cryocoolers based on Callaghan Innovation's diaphragm pressure wave generators (DPWGs). The pulse tube's lack of moving parts in combination with the DPWG's metal diaphragms produces a cost-effective, long-life, and robust cryocooler. The DPWG has had ten years of development, resulting in a series of DPWGs ranging in ... View full abstract»

Magnetic fields can be effectively shielded with superconducting tapes. They can be used either to attenuate a magnetic field or to improve its homogeneity. In this paper, magnetic field changes, due to the presence of a superconducting shield, are investigated. Both experimental and model results are shown. Specimens were subjected to a low-frequency ac magnetic field (up to 45 Hz). Attenuation o... View full abstract»

We developed a technique for fabricating (100)-oriented NbN thin films on Si (100) wafers by dc magnetron sputtering using TiN as a buffer layer. The lattice constant of the TiN buffer layer measured using X-ray diffraction was 0.4242 nm, which is relatively close to the NbN lattice constant of 0.446 nm. Therefore, NbN on the TiN buffer layer was epitaxially grown along the (100) direction. The ju... View full abstract»
