Abstract:
A mounting structure for a superconductor device housed in a closed vacuum chamber, said superconductor device adapted to have a signal inputted from a first external device and to output a signal to a second external device and comprising: a dielectric substrate having first and second surfaces; a circuit layer made of a superconducting thin film and deposited on said first surface of said dielectric substrate to allow said inputted signal to pass therethrough; and a ground layer made of a conductive material and deposited on said second surface of said dielectric substrate,said mounting structure comprising:a device holder having a base surface and adapted to hold said superconductor device thereon;a conductive layer intervening between said ground layer of said superconductor device and said device holder, and having a first surface facing said ground layer of said superconductor device and a second surface facing said base surface of said device holder, said base surface of said device holder and said ground layer of said superconductor device electrically connected with each other through said conductive layer;an input connector electrically connected to said superconductor device and said first external device to allow said signal to be inputted from said first external device to said superconductor device;an output connector electrically connected to said superconductor device and said second external device to allow said signal to be outputted from said superconductor device to said second external device; andfastening means for resiliently fastening said superconductor device to said device holder to have said first surface of said conductive layer held in press contact with said ground layer of said superconductor device and to have said second surface of said conductive layer held in press contact with said base surface of said device holder to ensure that said ground layer of said superconductor device is electrically connect to said device holder through said conductive layer,wherein said fastening means comprising a plurality of plate springs each positioned at each of said contact areas of said conductive layer to have said first surface of said conductive layer held in press contact with said ground layer of said superconductor device and to have said second surface of said conductive layer held in press contact with said base surface of said device holder to ensure that said ground layer of said superconductor device is electrically connected to said device holder through each of said contact areas of said conductive layer.
